And with mingw-w64 compilers, malloc.h already defines alloca. Is this the stdlib.h that comes with mingw-w64? Can you show the code that does that inclusion? Is it a simple #include <malloc.h> or is it protected by an #if or #ifdef? Also, how does malloc.h define alloca? Presumably it does not look like this: #define alloca __builtin_alloca so what does it look like? And is it defined unconditionally, or is it protected by an #if? That's the sort of thing I'm interested in. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
