    168 // 			to 1 or 0; the subsequent macros are either defined
    169 // 			or undefined, and those tests should be moved to
    170 // 			__GLIBC_USE.
    171 //    __USE_ISOC11		Define ISO C11 things.
    172 //    __USE_ISOC99		Define ISO C99 things.
    173 //    __USE_ISOC95		Define ISO C90 AMD1 (C95) things.

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

    220 //    ... code requiring gcc 2.8 or later ...
    221 //    #endif

    224 
    225 // Similarly for clang.  Features added to GCC after version 4.2 may
    226 //    or may not also be available in clang, and clang's definitions of
    227 //    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such

    234 //    issue a warning; the expectation is that the source is being
    235 //    transitioned to use the new macro.
    236 
    237 // If _GNU_SOURCE was defined by the user, turn on all the other features.
    238

    249 
    250 // If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE

    253 
    254 // Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
    255 //    defined in all multithreaded code.  GNU libc has not required this
    256 //    for many years.  We now treat them as compatibility synonyms for
    257 //    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
    258 //    comprehensive support for multithreaded code.  Using them never
    259 //    lowers the selected level of POSIX conformance, only raises it.
    260 
    261 // The function 'gets' existed in C89, but is impossible to use

    264 //    must consider only the value of __cplusplus when compiling C++.
    265 
    266 // GNU formerly extended the scanf functions with modified format
    267 //    specifiers %as, %aS, and %a[...] that allocate a buffer for the
    268 //    input using malloc.  This extension conflicts with ISO C99, which
    269 //    defines %a as a standalone format specifier that reads a floating-
    270 //    point number; moreover, POSIX.1-2008 provides the same feature
    271 //    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
    272 //
    273 //    We now follow C99 unless GNU extensions are active and the compiler
    274 //    is specifically in C89 or C++98 mode (strict or not).  For
    275 //    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
    276 //    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
    277 //    old extension.
