/* 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). */ #ifndef _ANSIDECL_H_ #define _ANSIDECL_H_ #include <sys/config.h> /* First try to figure out whether we really are in an ANSI C environment. */ /* FIXME: This probably needs some work.
