#ifndef _FEATURES_H
#define _FEATURES_H 1
/* These are defined by the user (or the compiler)
to specify the desired environment:
__STRICT_ANSI__ ISO Standard C.
_ISOC9X_SOURCE Extensions to ISO C 89 from ISO C 9x.
_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
_XOPEN_SOURCE Includes POSIX and XPG things. Set to 500 if
Single Unix conformance is wanted.
_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.
_BSD_SOURCE ISO C, POSIX, and 4.3BSD things.
_SVID_SOURCE ISO C, POSIX, and SVID things.
_GNU_SOURCE All of the above, plus GNU extensions.
_REENTRANT Select additionally reentrant object.
_THREAD_SAFE Same as _REENTRANT, often used by other systems.
The `-ansi' switch to the GNU C compiler defines __STRICT_ANSI__.
If none of these are defined, the default is all but _GNU_SOURCE.
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:
__USE_ISOC9X Define ISO C 9X things.
__USE_POSIX Define IEEE Std 1003.1 things.
__USE_POSIX2 Define IEEE Std 1003.2 things.
__USE_POSIX199309 Define IEEE Std 1003.1b things.
__USE_XOPEN Define XPG things.
__USE_XOPEN_EXTENDED Define X/Open Unix things.
__USE_UNIX98 Define Single Unix V2 things.
__USE_LARGEFILE64 Define LFS things with separate names.
__USE_FILE_OFFSET64 Define 64bit interface as default.
__USE_BSD Define 4.3BSD things.
__USE_SVID Define SVID things.
__USE_MISC Define things common to BSD and System V Unix.
__USE_GNU Define GNU extensions.
__USE_REENTRANT Define reentrant/thread-safe *_r functions.
__FAVOR_BSD Favor 4.3BSD things in cases of conflict.
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. */

<gnu/stubs.h> contains `#define __stub_FUNCTION' when FUNCTION is a stub
which will always return failure (and set errno to ENOSYS).
We avoid including <gnu/stubs.h> when compiling the C library itself to
avoid a dependency loop. stubs.h depends on every object file. If
this #include were done for the library source code, then every object
file would depend on stubs.h. */
