- 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). */
