+ _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.
+ _GNU_SOURCE All of the above, plus GNU extensions.
+ _DEFAULT_SOURCE The default set of features (taking precedence over
+ __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_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
+ , which does not have a multiple include
+ guard. Feature test macros that can be handled from the first
+ system header included are handled here. */
