Well, my solution would work as a replacement, too:
#define ALLOCA(siz) \
extern unsigned long _size_of_stack_reserve__; \
register char *_curstack __asm__ ("%esp"); \
size_t size = (siz); \
((size_t) ((_curstack - (_tlsbase \
- (size_t) &_size_of_stack_reserve__) \
) / 65536) * 65536 > size) ? alloca (size) : NULL;\
