/* 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). */
