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.
