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

+//
+// __GLIBC_USE (F) Define things from feature set F. This is defined

+// __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.

+// 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__
+//

+// 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.
