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

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

+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __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 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.

+// The GNU libc does not support any K&R compilers or the traditional mode

+
+// 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
