for broken old programs. The case conversion arrays are of `int's

the arrays are also used for multi-byte character sets. */

_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.
_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
<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. */
