Why should windows sources need to use __alloca.

If someone really wants an MSCV compatible (one underscore)  _alloca they just
add this to their srcs
void *_alloca (size_t size) {return __builtin_alloca (size));


MSDN documentation says that "This function is deprecated because a more secure
version is available; see _malloca."
