+// The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+// defined by this file unconditionally. `__GNU_LIBRARY__' is provided
+// only for compatibility. All new code should use the other symbols
+// to test for features.
+//
+// All macros listed above as possibly being defined by this file are
+// explicitly undefined if they are not explicitly defined.
+// Feature-test macros that are not defined by the user or compiler
+// but are implied by the other feature-test macros defined (or by the
+// lack of any definitions) are defined by the file.
+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first
+// system header included are handled here.

+// Undefine everything, so we get a clean slate.

+// Convenience macro to test the version of gcc.
+// Use like this:
+// #if __GNUC_PREREQ (2,8)
+// ... code requiring gcc 2.8 or later ...
+// #endif
+// Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of
+// __GNUC(_MINOR)__ are fixed at 4 and 2 respectively. Not all such
+// features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+// _DEFAULT_SOURCE. If _DEFAULT_SOURCE is present we do not
+// issue a warning; the expectation is that the source is being
+// transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+// is defined, use POSIX.1-2008 (or another version depending on
+// _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+// defined in all multithreaded code. GNU libc has not required this
+// for many years. We now treat them as compatibility synonyms for
+// _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+// comprehensive support for multithreaded code. Using them never
+// lowers the selected level of POSIX conformance, only raises it.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first
+// argument to strncpy and strncat, as the char array is not necessarily

+//
+// The `-ansi' switch to the GNU C compiler, and standards conformance
+// options such as `-std=c99', define __STRICT_ANSI__. If none of
+// these are defined, or if _DEFAULT_SOURCE is defined, the default is
+// to have _POSIX_SOURCE set to one and _POSIX_C_SOURCE set to
+// 200809L, as well as enabling miscellaneous functions from BSD and
+// SVID. If more than one of these are defined, they accumulate. For
+// example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE together
+// give you ISO C, 1003.1, and 1003.2, but nothing else.
+//
+// These are defined by this file and are used by the
+// header files to decide what to declare or define:
+//
+// __GLIBC_USE (F) Define things from feature set F. This is defined
+// to 1 or 0; the subsequent macros are either defined
+// or undefined, and those tests should be moved to
+// __GLIBC_USE.
+// __USE_ISOC11 Define ISO C11 things.
+// __USE_ISOC99 Define ISO C99 things.
+// __USE_ISOC95 Define ISO C90 AMD1 (C95) things.
+// __USE_ISOCXX11 Define ISO C++11 things.
+// __USE_POSIX Define IEEE Std 1003.1 things.
+// __USE_POSIX2 Define IEEE Std 1003.2 things.
+// __USE_POSIX199309 Define IEEE Std 1003.1, and .1b things.
+// __USE_POSIX199506 Define IEEE Std 1003.1, .1b, .1c and .1i things.
+// __USE_XOPEN Define XPG things.
+// __USE_XOPEN_EXTENDED Define X/Open Unix things.
+// __USE_UNIX98 Define Single Unix V2 things.

+// __USE_LARGEFILE Define correct standard I/O things.
+// __USE_LARGEFILE64 Define LFS things with separate names.
+// __USE_FILE_OFFSET64 Define 64bit interface as default.
+// __USE_MISC Define things from 4.3BSD or System V Unix.
+// __USE_ATFILE Define *at interfaces and AT_* constants for them.
+// __USE_DYNAMIC_STACK_SIZE Define correct (but non compile-time constant)
+// MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
+// __USE_GNU Define GNU extensions.
+// __USE_FORTIFY_LEVEL Additional security measures used, according to level.
+//
+// The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+// defined by this file unconditionally. `__GNU_LIBRARY__' is provided
+// only for compatibility. All new code should use the other symbols
+// to test for features.
+//
+// All macros listed above as possibly being defined by this file are
+// explicitly undefined if they are not explicitly defined.
+// Feature-test macros that are not defined by the user or compiler
+// but are implied by the other feature-test macros defined (or by the
+// lack of any definitions) are defined by the file.
+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first
+// system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+// for it.
+
+// Convenience macro to test the version of gcc.
+// Use like this:
+// #if __GNUC_PREREQ (2,8)
+// ... code requiring gcc 2.8 or later ...
+// #endif
+// Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of
+// __GNUC(_MINOR)__ are fixed at 4 and 2 respectively. Not all such
+// features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+// _DEFAULT_SOURCE. If _DEFAULT_SOURCE is present we do not
+// issue a warning; the expectation is that the source is being
+// transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+// is defined, use POSIX.1-2008 (or another version depending on
+// _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+// defined in all multithreaded code. GNU libc has not required this
+// for many years. We now treat them as compatibility synonyms for
+// _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+// comprehensive support for multithreaded code. Using them never
+// lowers the selected level of POSIX conformance, only raises it.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE

+// We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+// variants of each of the following integer types on this machine.
+//
+// 16 -- "natural" 16-bit type (always short)
+// 32 -- "natural" 32-bit type (always int)
+// 64 -- "natural" 64-bit type (long or long long)
+// LONG32 -- 32-bit type, traditionally long
+// QUAD -- 64-bit type, traditionally long long
+// WORD -- natural type of __WORDSIZE bits (int or long)
+// LONGWORD -- type of __WORDSIZE bits, traditionally long
+//
+// We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+// conventional uses of `long' or `long long' type modifiers match the
+// types we define, even when a less-adorned type would be the same size.
+// This matters for (somewhat) portably writing printf/scanf formats for
+// these types, where using the appropriate l or ll format modifiers can
+// make the typedefs and the formats match up across all GNU platforms. If
+// we used `long' when it's 64 bits where `long long' is expected, then the
+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.
+//
+// Here we assume what is presently the case in all the GCC configurations
+// we support: long long is always 64 bits, long is always word/address size,
+// and int is always 32 bits.
+
+// No need to mark the typedef with __extension__.

+//
+// These are defined by this file and are used by the
+// header files to decide what to declare or define:
+//
+// __GLIBC_USE (F) Define things from feature set F. This is defined
+// to 1 or 0; the subsequent macros are either defined
+// or undefined, and those tests should be moved to
+// __GLIBC_USE.
+// __USE_ISOC11 Define ISO C11 things.
+// __USE_ISOC99 Define ISO C99 things.
+// __USE_ISOC95 Define ISO C90 AMD1 (C95) things.
+// __USE_ISOCXX11 Define ISO C++11 things.
+// __USE_POSIX Define IEEE Std 1003.1 things.
+// __USE_POSIX2 Define IEEE Std 1003.2 things.
+// __USE_POSIX199309 Define IEEE Std 1003.1, and .1b things.
+// __USE_POSIX199506 Define IEEE Std 1003.1, .1b, .1c and .1i things.
+// __USE_XOPEN Define XPG things.
+// __USE_XOPEN_EXTENDED Define X/Open Unix things.
+// __USE_UNIX98 Define Single Unix V2 things.
+// __USE_XOPEN2K Define XPG6 things.
+// __USE_XOPEN2KXSI Define XPG6 XSI things.
+// __USE_XOPEN2K8 Define XPG7 things.
+// __USE_XOPEN2K8XSI Define XPG7 XSI things.
+// __USE_LARGEFILE Define correct standard I/O things.
+// __USE_LARGEFILE64 Define LFS things with separate names.
+// __USE_FILE_OFFSET64 Define 64bit interface as default.
+// __USE_MISC Define things from 4.3BSD or System V Unix.
+// __USE_ATFILE Define *at interfaces and AT_* constants for them.
+// __USE_DYNAMIC_STACK_SIZE Define correct (but non compile-time constant)
+// MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
+// __USE_GNU Define GNU extensions.
+// __USE_FORTIFY_LEVEL Additional security measures used, according to level.
+//
+// The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+// defined by this file unconditionally. `__GNU_LIBRARY__' is provided
+// only for compatibility. All new code should use the other symbols
+// to test for features.
+//
+// All macros listed above as possibly being defined by this file are
+// explicitly undefined if they are not explicitly defined.
+// Feature-test macros that are not defined by the user or compiler
+// but are implied by the other feature-test macros defined (or by the
+// lack of any definitions) are defined by the file.
+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first
+// system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+// for it.
+
+// Convenience macro to test the version of gcc.
+// Use like this:
+// #if __GNUC_PREREQ (2,8)
+// ... code requiring gcc 2.8 or later ...
+// #endif
+// Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of
+// __GNUC(_MINOR)__ are fixed at 4 and 2 respectively. Not all such
+// features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+// _DEFAULT_SOURCE. If _DEFAULT_SOURCE is present we do not
+// issue a warning; the expectation is that the source is being
+// transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+// is defined, use POSIX.1-2008 (or another version depending on
+// _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+// defined in all multithreaded code. GNU libc has not required this
+// for many years. We now treat them as compatibility synonyms for
+// _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+// comprehensive support for multithreaded code. Using them never
+// lowers the selected level of POSIX conformance, only raises it.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first

+// All macros listed above as possibly being defined by this file are

+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system

+
+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first
+// argument to strncpy and strncat, as the char array is not necessarily
+// a NUL-terminated string.
+
+// Undefine (also defined in libc-symbols.h).
+// Copies attributes from the declaration or type referenced by

+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.

+// Some user header file might have defined this before.

+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.

+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:

+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)

+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,

+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.

+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
+// macros for each of the OS types we define below. The definitions
+// of those macros must use the following macros for underlying types.
+// We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+// variants of each of the following integer types on this machine.
+//
+// 16 -- "natural" 16-bit type (always short)
+// 32 -- "natural" 32-bit type (always int)
+// 64 -- "natural" 64-bit type (long or long long)
+// LONG32 -- 32-bit type, traditionally long
+// QUAD -- 64-bit type, traditionally long long
+// WORD -- natural type of __WORDSIZE bits (int or long)
+// LONGWORD -- type of __WORDSIZE bits, traditionally long
+//
+// We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+// conventional uses of `long' or `long long' type modifiers match the
+// types we define, even when a less-adorned type would be the same size.
+// This matters for (somewhat) portably writing printf/scanf formats for
+// these types, where using the appropriate l or ll format modifiers can
+// make the typedefs and the formats match up across all GNU platforms. If
+// we used `long' when it's 64 bits where `long long' is expected, then the
+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.
+//
+// Here we assume what is presently the case in all the GCC configurations
+// we support: long long is always 64 bits, long is always word/address size,
+// and int is always 32 bits.
+
+// No need to mark the typedef with __extension__.

+//
+// All macros listed above as possibly being defined by this file are

+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first
+// system header included are handled here.

+// Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first

+// All macros listed above as possibly being defined by this file are

+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first

+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of

+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.

+
+// This is to enable the ISO C11 extension.

+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be

+// GNU formerly extended the scanf functions with modified format
+// specifiers %as, %aS, and %a[...] that allocate a buffer for the
+// input using malloc. This extension conflicts with ISO C99, which
+// defines %a as a standalone format specifier that reads a floating-

+// We now follow C99 unless GNU extensions are active and the compiler
+// is specifically in C89 or C++98 mode (strict or not). For
+// instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+// or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.

+//
+// These are defined by this file and are used by the
+// header files to decide what to declare or define:
+//
+// __GLIBC_USE (F) Define things from feature set F. This is defined
+// to 1 or 0; the subsequent macros are either defined
+// or undefined, and those tests should be moved to
+// __GLIBC_USE.
+// __USE_ISOC11 Define ISO C11 things.
+// __USE_ISOC99 Define ISO C99 things.
+// __USE_ISOC95 Define ISO C90 AMD1 (C95) things.
+// __USE_ISOCXX11 Define ISO C++11 things.
+// __USE_POSIX Define IEEE Std 1003.1 things.
+// __USE_POSIX2 Define IEEE Std 1003.2 things.
+// __USE_POSIX199309 Define IEEE Std 1003.1, and .1b things.
+// __USE_POSIX199506 Define IEEE Std 1003.1, .1b, .1c and .1i things.
+// __USE_XOPEN Define XPG things.
+// __USE_XOPEN_EXTENDED Define X/Open Unix things.
+// __USE_UNIX98 Define Single Unix V2 things.

+// __USE_DYNAMIC_STACK_SIZE Define correct (but non compile-time constant)
+// MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
+// __USE_GNU Define GNU extensions.
+// __USE_FORTIFY_LEVEL Additional security measures used, according to level.
+//
+// The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+// defined by this file unconditionally. `__GNU_LIBRARY__' is provided
+// only for compatibility. All new code should use the other symbols
+// to test for features.
+//
+// All macros listed above as possibly being defined by this file are
+// explicitly undefined if they are not explicitly defined.
+// Feature-test macros that are not defined by the user or compiler
+// but are implied by the other feature-test macros defined (or by the
+// lack of any definitions) are defined by the file.
+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first
+// system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+// for it.
+
+// Convenience macro to test the version of gcc.
+// Use like this:
+// #if __GNUC_PREREQ (2,8)
+// ... code requiring gcc 2.8 or later ...
+// #endif
+// Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of
+// __GNUC(_MINOR)__ are fixed at 4 and 2 respectively. Not all such
+// features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+// _DEFAULT_SOURCE. If _DEFAULT_SOURCE is present we do not
+// issue a warning; the expectation is that the source is being
+// transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+// is defined, use POSIX.1-2008 (or another version depending on
+// _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+// defined in all multithreaded code. GNU libc has not required this
+// for many years. We now treat them as compatibility synonyms for
+// _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+// comprehensive support for multithreaded code. Using them never
+// lowers the selected level of POSIX conformance, only raises it.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first

+// QUAD -- 64-bit type, traditionally long long
+// WORD -- natural type of __WORDSIZE bits (int or long)
+// LONGWORD -- type of __WORDSIZE bits, traditionally long
+//
+// We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+// conventional uses of `long' or `long long' type modifiers match the
+// types we define, even when a less-adorned type would be the same size.
+// This matters for (somewhat) portably writing printf/scanf formats for
+// these types, where using the appropriate l or ll format modifiers can
+// make the typedefs and the formats match up across all GNU platforms. If
+// we used `long' when it's 64 bits where `long long' is expected, then the
+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.
+//
+// Here we assume what is presently the case in all the GCC configurations
+// we support: long long is always 64 bits, long is always word/address size,
+// and int is always 32 bits.

+// The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+// defined by this file unconditionally. `__GNU_LIBRARY__' is provided
+// only for compatibility. All new code should use the other symbols
+// to test for features.
+//
+// All macros listed above as possibly being defined by this file are
+// explicitly undefined if they are not explicitly defined.
+// Feature-test macros that are not defined by the user or compiler
+// but are implied by the other feature-test macros defined (or by the
+// lack of any definitions) are defined by the file.
+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first
+// system header included are handled here.

+// ... code requiring gcc 2.8 or later ...
+// #endif
+// Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of
+// __GNUC(_MINOR)__ are fixed at 4 and 2 respectively. Not all such
+// features can be queried via __has_extension/__has_feature.

+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+// _DEFAULT_SOURCE. If _DEFAULT_SOURCE is present we do not
+// issue a warning; the expectation is that the source is being

+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.

+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE

+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first
+// argument to strncpy and strncat, as the char array is not necessarily
+// a NUL-terminated string.
+
+// Undefine (also defined in libc-symbols.h).

+//
+// 16 -- "natural" 16-bit type (always short)

+// 64 -- "natural" 64-bit type (long or long long)
+// LONG32 -- 32-bit type, traditionally long
+// QUAD -- 64-bit type, traditionally long long
+// WORD -- natural type of __WORDSIZE bits (int or long)
+// LONGWORD -- type of __WORDSIZE bits, traditionally long
+//
+// We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+// conventional uses of `long' or `long long' type modifiers match the
+// types we define, even when a less-adorned type would be the same size.
+// This matters for (somewhat) portably writing printf/scanf formats for
+// these types, where using the appropriate l or ll format modifiers can
+// make the typedefs and the formats match up across all GNU platforms. If
+// we used `long' when it's 64 bits where `long long' is expected, then the
+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.
+//
+// Here we assume what is presently the case in all the GCC configurations
+// we support: long long is always 64 bits, long is always word/address size,
+// and int is always 32 bits.

+// LONGWORD -- type of __WORDSIZE bits, traditionally long

+// We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the

+// types we define, even when a less-adorned type would be the same size.
+// This matters for (somewhat) portably writing printf/scanf formats for
+// these types, where using the appropriate l or ll format modifiers can
+// make the typedefs and the formats match up across all GNU platforms. If
+// we used `long' when it's 64 bits where `long long' is expected, then the
+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.
+//
+// Here we assume what is presently the case in all the GCC configurations
+// we support: long long is always 64 bits, long is always word/address size,

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
+// macros for each of the OS types we define below. The definitions
+// of those macros must use the following macros for underlying types.
+// We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+// variants of each of the following integer types on this machine.
+//
+// 16 -- "natural" 16-bit type (always short)
+// 32 -- "natural" 32-bit type (always int)
+// 64 -- "natural" 64-bit type (long or long long)
+// LONG32 -- 32-bit type, traditionally long
+// QUAD -- 64-bit type, traditionally long long
+// WORD -- natural type of __WORDSIZE bits (int or long)
+// LONGWORD -- type of __WORDSIZE bits, traditionally long
+//
+// We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+// conventional uses of `long' or `long long' type modifiers match the
+// types we define, even when a less-adorned type would be the same size.
+// This matters for (somewhat) portably writing printf/scanf formats for
+// these types, where using the appropriate l or ll format modifiers can
+// make the typedefs and the formats match up across all GNU platforms. If
+// we used `long' when it's 64 bits where `long long' is expected, then the
+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.
+//
+// Here we assume what is presently the case in all the GCC configurations
+// we support: long long is always 64 bits, long is always word/address size,
+// and int is always 32 bits.
+
+// No need to mark the typedef with __extension__.

+//
+// All macros listed above as possibly being defined by this file are

+// Feature-test macros that are not defined by the user or compiler
+// but are implied by the other feature-test macros defined (or by the

+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in

+// guard. Feature test macros that can be handled from the first

+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of

+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for

+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.

+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+

+// These are defined by this file and are used by the

+// or undefined, and those tests should be moved to
+// __GLIBC_USE.
+// __USE_ISOC11 Define ISO C11 things.

+// __USE_ISOC95 Define ISO C90 AMD1 (C95) things.
+// __USE_ISOCXX11 Define ISO C++11 things.
+// __USE_POSIX Define IEEE Std 1003.1 things.
+// __USE_POSIX2 Define IEEE Std 1003.2 things.
+// __USE_POSIX199309 Define IEEE Std 1003.1, and .1b things.
+// __USE_POSIX199506 Define IEEE Std 1003.1, .1b, .1c and .1i things.
+// __USE_XOPEN Define XPG things.
+// __USE_XOPEN_EXTENDED Define X/Open Unix things.
+// __USE_UNIX98 Define Single Unix V2 things.

+// MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
+// __USE_GNU Define GNU extensions.
+// __USE_FORTIFY_LEVEL Additional security measures used, according to level.
+//
+// The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+// defined by this file unconditionally. `__GNU_LIBRARY__' is provided
+// only for compatibility. All new code should use the other symbols
+// to test for features.
+//
+// All macros listed above as possibly being defined by this file are
+// explicitly undefined if they are not explicitly defined.
+// Feature-test macros that are not defined by the user or compiler
+// but are implied by the other feature-test macros defined (or by the
+// lack of any definitions) are defined by the file.
+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first
+// system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+// for it.
+
+// Convenience macro to test the version of gcc.
+// Use like this:
+// #if __GNUC_PREREQ (2,8)
+// ... code requiring gcc 2.8 or later ...
+// #endif
+// Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of
+// __GNUC(_MINOR)__ are fixed at 4 and 2 respectively. Not all such
+// features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+// _DEFAULT_SOURCE. If _DEFAULT_SOURCE is present we do not
+// issue a warning; the expectation is that the source is being
+// transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+// is defined, use POSIX.1-2008 (or another version depending on
+// _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+// defined in all multithreaded code. GNU libc has not required this
+// for many years. We now treat them as compatibility synonyms for
+// _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+// comprehensive support for multithreaded code. Using them never
+// lowers the selected level of POSIX conformance, only raises it.

+// specifiers %as, %aS, and %a[...] that allocate a buffer for the
+// input using malloc. This extension conflicts with ISO C99, which
+// defines %a as a standalone format specifier that reads a floating-
+// point number; moreover, POSIX.1-2008 provides the same feature
+// using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+// We now follow C99 unless GNU extensions are active and the compiler
+// is specifically in C89 or C++98 mode (strict or not). For
+// instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+// or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+// old extension.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first

+// The `-ansi' switch to the GNU C compiler, and standards conformance
+// options such as `-std=c99', define __STRICT_ANSI__. If none of
+// these are defined, or if _DEFAULT_SOURCE is defined, the default is

+// 200809L, as well as enabling miscellaneous functions from BSD and
+// SVID. If more than one of these are defined, they accumulate. For

+//
+// These are defined by this file and are used by the
+// header files to decide what to declare or define:
+//
+// __GLIBC_USE (F) Define things from feature set F. This is defined
+// to 1 or 0; the subsequent macros are either defined
+// or undefined, and those tests should be moved to
+// __GLIBC_USE.
+// __USE_ISOC11 Define ISO C11 things.
+// __USE_ISOC99 Define ISO C99 things.
+// __USE_ISOC95 Define ISO C90 AMD1 (C95) things.
+// __USE_ISOCXX11 Define ISO C++11 things.
+// __USE_POSIX Define IEEE Std 1003.1 things.
+// __USE_POSIX2 Define IEEE Std 1003.2 things.
+// __USE_POSIX199309 Define IEEE Std 1003.1, and .1b things.
+// __USE_POSIX199506 Define IEEE Std 1003.1, .1b, .1c and .1i things.
+// __USE_XOPEN Define XPG things.
+// __USE_XOPEN_EXTENDED Define X/Open Unix things.
+// __USE_UNIX98 Define Single Unix V2 things.
+// __USE_XOPEN2K Define XPG6 things.

+// __USE_XOPEN2K8 Define XPG7 things.
+// __USE_XOPEN2K8XSI Define XPG7 XSI things.
+// __USE_LARGEFILE Define correct standard I/O things.
+// __USE_LARGEFILE64 Define LFS things with separate names.
+// __USE_FILE_OFFSET64 Define 64bit interface as default.
+// __USE_MISC Define things from 4.3BSD or System V Unix.
+// __USE_ATFILE Define *at interfaces and AT_* constants for them.
+// __USE_DYNAMIC_STACK_SIZE Define correct (but non compile-time constant)
+// MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
+// __USE_GNU Define GNU extensions.
+// __USE_FORTIFY_LEVEL Additional security measures used, according to level.
+//
+// The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+// defined by this file unconditionally. `__GNU_LIBRARY__' is provided
+// only for compatibility. All new code should use the other symbols
+// to test for features.
+//
+// All macros listed above as possibly being defined by this file are
+// explicitly undefined if they are not explicitly defined.
+// Feature-test macros that are not defined by the user or compiler
+// but are implied by the other feature-test macros defined (or by the
+// lack of any definitions) are defined by the file.
+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first
+// system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+// for it.
+
+// Convenience macro to test the version of gcc.
+// Use like this:
+// #if __GNUC_PREREQ (2,8)
+// ... code requiring gcc 2.8 or later ...
+// #endif
+// Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of
+// __GNUC(_MINOR)__ are fixed at 4 and 2 respectively. Not all such
+// features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+// _DEFAULT_SOURCE. If _DEFAULT_SOURCE is present we do not
+// issue a warning; the expectation is that the source is being
+// transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+// is defined, use POSIX.1-2008 (or another version depending on
+// _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+// defined in all multithreaded code. GNU libc has not required this
+// for many years. We now treat them as compatibility synonyms for
+// _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+// comprehensive support for multithreaded code. Using them never
+// lowers the selected level of POSIX conformance, only raises it.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE

+// of those macros must use the following macros for underlying types.
+// We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+// variants of each of the following integer types on this machine.
+//
+// 16 -- "natural" 16-bit type (always short)
+// 32 -- "natural" 32-bit type (always int)
+// 64 -- "natural" 64-bit type (long or long long)
+// LONG32 -- 32-bit type, traditionally long
+// QUAD -- 64-bit type, traditionally long long
+// WORD -- natural type of __WORDSIZE bits (int or long)
+// LONGWORD -- type of __WORDSIZE bits, traditionally long
+//
+// We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+// conventional uses of `long' or `long long' type modifiers match the
+// types we define, even when a less-adorned type would be the same size.
+// This matters for (somewhat) portably writing printf/scanf formats for
+// these types, where using the appropriate l or ll format modifiers can
+// make the typedefs and the formats match up across all GNU platforms. If
+// we used `long' when it's 64 bits where `long long' is expected, then the
+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.
+//
+// Here we assume what is presently the case in all the GCC configurations
+// we support: long long is always 64 bits, long is always word/address size,
+// and int is always 32 bits.
+
+// No need to mark the typedef with __extension__.

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE

+// of those macros must use the following macros for underlying types.
+// We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+// variants of each of the following integer types on this machine.
+//
+// 16 -- "natural" 16-bit type (always short)
+// 32 -- "natural" 32-bit type (always int)
+// 64 -- "natural" 64-bit type (long or long long)
+// LONG32 -- 32-bit type, traditionally long
+// QUAD -- 64-bit type, traditionally long long
+// WORD -- natural type of __WORDSIZE bits (int or long)
+// LONGWORD -- type of __WORDSIZE bits, traditionally long
+//
+// We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+// conventional uses of `long' or `long long' type modifiers match the
+// types we define, even when a less-adorned type would be the same size.
+// This matters for (somewhat) portably writing printf/scanf formats for
+// these types, where using the appropriate l or ll format modifiers can
+// make the typedefs and the formats match up across all GNU platforms. If
+// we used `long' when it's 64 bits where `long long' is expected, then the
+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.
+//
+// Here we assume what is presently the case in all the GCC configurations
+// we support: long long is always 64 bits, long is always word/address size,
+// and int is always 32 bits.
+
+// No need to mark the typedef with __extension__.

+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system

+// guard. Feature test macros that can be handled from the first

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.

+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.

+// These are defined by this file and are used by the

+// or undefined, and those tests should be moved to

+// __USE_POSIX199309 Define IEEE Std 1003.1, and .1b things.
+// __USE_POSIX199506 Define IEEE Std 1003.1, .1b, .1c and .1i things.
+// __USE_XOPEN Define XPG things.
+// __USE_XOPEN_EXTENDED Define X/Open Unix things.

+// MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
+// __USE_GNU Define GNU extensions.
+// __USE_FORTIFY_LEVEL Additional security measures used, according to level.
+//
+// The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+// defined by this file unconditionally. `__GNU_LIBRARY__' is provided
+// only for compatibility. All new code should use the other symbols
+// to test for features.
+//
+// All macros listed above as possibly being defined by this file are
+// explicitly undefined if they are not explicitly defined.
+// Feature-test macros that are not defined by the user or compiler
+// but are implied by the other feature-test macros defined (or by the
+// lack of any definitions) are defined by the file.
+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first
+// system header included are handled here.
+
+// Undefine everything, so we get a clean slate.

+// Convenience macro to test the version of gcc.
+// Use like this:

+// ... code requiring gcc 2.8 or later ...
+// #endif
+// Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of
+// __GNUC(_MINOR)__ are fixed at 4 and 2 respectively. Not all such
+// features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+// _DEFAULT_SOURCE. If _DEFAULT_SOURCE is present we do not
+// issue a warning; the expectation is that the source is being
+// transitioned to use the new macro.

+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+// is defined, use POSIX.1-2008 (or another version depending on
+// _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+// defined in all multithreaded code. GNU libc has not required this
+// for many years. We now treat them as compatibility synonyms for
+// _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with

+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+
+// Describes a char array whose address can safely be passed as the first

+// The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+// defined by this file unconditionally. `__GNU_LIBRARY__' is provided
+// only for compatibility. All new code should use the other symbols
+// to test for features.
+//
+// All macros listed above as possibly being defined by this file are
+// explicitly undefined if they are not explicitly defined.
+// Feature-test macros that are not defined by the user or compiler
+// but are implied by the other feature-test macros defined (or by the
+// lack of any definitions) are defined by the file.
+//
+// ISO C feature test macros depend on the definition of the macro
+// when an affected header is included, not when the first system
+// header is included, and so they are handled in
+// <bits/libc-header-start.h>, which does not have a multiple include
+// guard. Feature test macros that can be handled from the first
+// system header included are handled here.
+
+// Undefine everything, so we get a clean slate.

+// Convenience macro to test the version of gcc.
+// Use like this:
+// #if __GNUC_PREREQ (2,8)
+// ... code requiring gcc 2.8 or later ...
+// #endif
+// Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+// added in 2.0.
+
+// Similarly for clang. Features added to GCC after version 4.2 may
+// or may not also be available in clang, and clang's definitions of
+// __GNUC(_MINOR)__ are fixed at 4 and 2 respectively. Not all such
+// features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+// _DEFAULT_SOURCE. If _DEFAULT_SOURCE is present we do not
+// issue a warning; the expectation is that the source is being
+// transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+// define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+// is defined, use POSIX.1-2008 (or another version depending on
+// _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+// defined in all multithreaded code. GNU libc has not required this
+// for many years. We now treat them as compatibility synonyms for
+// _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+// comprehensive support for multithreaded code. Using them never
+// lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+// safely. It has been removed from ISO C11 and ISO C++14. Note: for
+// compatibility with various implementations of <cstdio>, this test
+// must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+// specifiers %as, %aS, and %a[...] that allocate a buffer for the
+// input using malloc. This extension conflicts with ISO C99, which
+// defines %a as a standalone format specifier that reads a floating-
+// point number; moreover, POSIX.1-2008 provides the same feature
+// using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+// We now follow C99 unless GNU extensions are active and the compiler
+// is specifically in C89 or C++98 mode (strict or not). For
+// instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+// or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+// old extension.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// anymore supported.
+
+// Some user header file might have defined this before.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this works only with
+// gcc 2.8.x and egcs. For gcc 3.2 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+// #if defined __clang__ && __has_extension(...)
+// even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+// `__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+// must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]

+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+// of ISO C compilers anymore. Check for some of the combinations not
+// supported anymore.
+
+// Some user header file might have defined this before.
+
+// Compilers that lack __has_attribute may object to
+// #if defined __has_attribute && __has_attribute (...)
+// even though they do not need to evaluate the right-hand side of the &&.
+// Similarly for __has_builtin, etc.
+
+// All functions, except those with callbacks or those that
+// synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes. For C++ programs we add throw()
+// to help it optimize the function calls. But this only works with
+// gcc 2.8.x and egcs. For gcc 3.4 and up we even mark C functions
+// as non-throwing using a function attribute since programs can use
+// the -fexceptions options for C code as well.
+
+// These two macros are not used in glibc anymore. They are kept here
+// only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+// and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Use __builtin_dynamic_object_size at _FORTIFY_SOURCE=3 when available.
+
+// Support for flexible arrays.
+// Headers that should use flexible arrays only if they're "real"
+// (e.g. only if they won't affect sizeof()) should test
+// #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+// at the assembly language level. This is wrapped by the __REDIRECT
+// macro, in order to support compilers that can do this some other
+// way. When compilers don't support asm-names at all, we have to do
+// preprocessor tricks instead (which don't have exactly the right
+// semantics, but it's the best we can do).
+//
+// Example:
+// int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; _Pragma("let " #name " = " #alias)
+
+// GCC and clang have various useful declarations that can be made with
+// the '__attribute__' syntax. All of the ways we use this do fine if
+// they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+// indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+// when a deprecated function is used. clang claims to be gcc 4.2, but
+// may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+// for functions was introduced. We don't want to use it unconditionally
+// (although this would be possible) since it generates warnings.
+// If several `format_arg' attributes are given for the same function, in
+// gcc-3.0 and older, all but the last one are ignored. In newer gccs,
+// all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+// attribute for functions was introduced. We don't want to use it
+// unconditionally (although this would be possible) since it
+// generates warnings.
+
+// The nonnull function attribute marks pointer parameters that
+// must not be NULL.
+
+// The returns_nonnull function attribute marks the return type of the function
+// as always being non-null.
+
+// If fortification mode, we warn about unused results of certain
+// function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+// it conflicts with this definition. Therefore undefine it first to
+// allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+// than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+// inline semantics, unless -fgnu89-inline is used. Using __GNUC_STDC_INLINE__
+// or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+// older than 4.3 may define these macros and still not guarantee GNU inlining
+// semantics.
+//
+// clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+// semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+// __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+// __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+// run in pedantic mode if the uses are carefully marked using the
+// `__extension__' keyword. But this is not generally available before
+// version 2.8.
+
+// __restrict is known in EGCS 1.2 and above, and in clang.
+// It works also in C++ mode (outside of arrays), but only when spelled
+// as '__restrict', not 'restrict'.
+
+// ISO C99 also allows to declare arrays as non-overlapping. The syntax is
+// array_name[restrict]
+// GCC 3.1 and clang support this.
+// This syntax is not usable in C++ mode.
+

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
+// macros for each of the OS types we define below. The definitions
+// of those macros must use the following macros for underlying types.
+// We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+// variants of each of the following integer types on this machine.
+//
+// 16 -- "natural" 16-bit type (always short)
+// 32 -- "natural" 32-bit type (always int)
+// 64 -- "natural" 64-bit type (long or long long)
+// LONG32 -- 32-bit type, traditionally long
+// QUAD -- 64-bit type, traditionally long long
+// WORD -- natural type of __WORDSIZE bits (int or long)
+// LONGWORD -- type of __WORDSIZE bits, traditionally long
+//
+// We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+// conventional uses of `long' or `long long' type modifiers match the
+// types we define, even when a less-adorned type would be the same size.
+// This matters for (somewhat) portably writing printf/scanf formats for
+// these types, where using the appropriate l or ll format modifiers can
+// make the typedefs and the formats match up across all GNU platforms. If
+// we used `long' when it's 64 bits where `long long' is expected, then the
+// compiler would warn about the formats not matching the argument types,
+// and the programmer changing them to shut up the compiler would break the
+// program's portability.
+//
+// Here we assume what is presently the case in all the GCC configurations
+// we support: long long is always 64 bits, long is always word/address size,
+// and int is always 32 bits.
+
+// No need to mark the typedef with __extension__.
