+// These are defined by the user (or the compiler)
+//    to specify the desired environment:

+//    _ISOC11_SOURCE	Extensions to ISO C99 from ISO C11.
+//    _ISOC2X_SOURCE	Extensions to ISO C99 from ISO C2X.

+// 			Extensions to ISO C11 from TS 18661-3:2015.
+//    __STDC_WANT_IEC_60559_EXT__
+// 			ISO C2X interfaces defined only in Annex F.
+//
+//    _POSIX_SOURCE	IEEE Std 1003.1.
+//    _POSIX_C_SOURCE	If ==1, like _POSIX_SOURCE; if >=2 add IEEE Std 1003.2;
+// 			if >=199309L, add IEEE Std 1003.1b-1993;
+// 			if >=199506L, add IEEE Std 1003.1c-1995;
+// 			if >=200112L, all of IEEE 1003.1-2004
+// 			if >=200809L, all of IEEE 1003.1-2008
+//    _XOPEN_SOURCE	Includes POSIX and XPG things.  Set to 500 if
+// 			Single Unix conformance is wanted, to 600 for the
+// 			sixth revision, to 700 for the seventh revision.
+//    _XOPEN_SOURCE_EXTENDED XPG things and X/Open Unix extensions.
+//    _LARGEFILE_SOURCE	Some more functions for correct standard I/O.
+//    _LARGEFILE64_SOURCE	Additional functionality from LFS for large files.
+//    _FILE_OFFSET_BITS=N	Select default filesystem interface.
+//    _ATFILE_SOURCE	Additional *at interfaces.
+//    _DYNAMIC_STACK_SIZE_SOURCE Select correct (but non compile-time constant)

+// 			__STRICT_ANSI__).
+//
+//    _FORTIFY_SOURCE	Add security hardening to many library functions.
+// 			Set to 1 or 2; 2 performs stricter checks than 1.
+//
+//    _REENTRANT, _THREAD_SAFE
+// 			Obsolete; equivalent to _POSIX_C_SOURCE=199506L.
+//
+//    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_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.

+
+// 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

+
+// 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

+//    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.

+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned

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

+// 	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,
