Required some nasty frontend hacks to trick the GCC backend into thinking it
was dealing with a C ABI va_list type (and to not ICE it's way to Budapest and
back), but pretty much done now.


- va_list treated is as void*
- __va_list is the C ABI va_list.


I'd not be too surprised if architectures where va_list is neither a pointer or
array are broken now (such as ARM, where I'd imagine there'd be a nop cast from
void* to struct) - but see how it goes when it hits the Debian repository...

Closing this report as fixed, and *don't* raise a bug about 64bit va_args,
va_argsave, or whatever. As that ugly mess will never be implemented ( on my
watch :)
