On mingw, this function is only available if such a version of the
MSVCRT is targeted that contain it, controlled via the
headers. Currently, since this doesn't test the headers but only tests
linking, it will succeed regardless. A check which tries to include it
from the header (malloc.h) would be better in this case, I think.

Do you have such a system?  Could you help testing it?

Yes, I can try to make a better version of this patch and test it as far as I can :-)
