STDC_HEADERS is in the user's space, so the system stdlib.h should be unaffected by whether STDC_HEADERS is defined. Are we talking about the system's stdlib.h here, or by your own substitute for stdlib.h? If the latter, then it might be something outside the scope of the autoconf documentation.
there was a warning when using mingw-w64 compilers : redefinition of alloca. The line where the redefinition is located is:
#elif defined __GNUC__ # define alloca __builtin_alloca <---- that oneand there was a redefinition because stdlib.h is included just above, and stdlib.h includes malloc.h. And with mingw-w64 compilers, malloc.h already defines alloca.
I hope I'm clearer :) Vincent Torri _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
