+/* Provide support for both ANSI and non-ANSI environments.  */

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