[Zlib-devel] Is gcc always STDC?

[Cosmin Truta]

Hi,

Regarding Charles Wilson's latest Cygwin patch, I would like to change
his suggestion


-#if (defined(MSDOS) || defined(_WINDOWS) || defined(WIN32))  && !defined(STDC)
+#if (defined(MSDOS) || defined(_WINDOWS) || defined(WIN32) || defined(__CYGWIN__))  && !defined(STDC)
 #  define STDC
 #endif


into something like


#if defined(__STDC__) || defined(__cplusplus) || defined(__GNUC__)
#  ifndef STDC
#    define STDC
#  endif
#endif

#if defined(MSDOS) || defined(_WINDOWS) || defined(WIN32)
#  ifndef STDC
#    define STDC
#  endif
#endif

#if defined(__OS2__) || defined(__HOS_AIX__)
#  ifndef STDC
#    define STDC
#  endif
#endif


Can we say that gcc is always STDC? If yes, then we shouldn't need
__CYGWIN__ (or __linux, etc.) and this should work even when ./configure
is not run.
