/* Provide support for both ANSI and non-ANSI environments.  */
2
 
3
/* Some ANSI environments are "broken" in the sense that __STDC__ cannot be
4
   relied upon to have it's intended meaning.  Therefore we must use our own
5
   concoction: _HAVE_STDC.  Always use _HAVE_STDC instead of __STDC__ in newlib
6
   sources!
7
 
8
   To get a strict ANSI C environment, define macro __STRICT_ANSI__.  This will
9
   "comment out" the non-ANSI parts of the ANSI header files (non-ANSI header
10
   files aren't affected).  */
