#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.
   _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.
   _XOPEN_SOURCE_EXTENDED XPG things and X/Open Unix extensions.
   _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_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_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.  */
