   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).  */
