Well, this sounds good. I wasn't aware that __UINTPTR_TYPE__ is
present. I just was aware of the SIZE, and PTRDIFF builtin macros,
which aren't useful here for all targets.
Maybe a __ULONGPTR_TYPE__ should be added as internal macro, too.
Because sometimes the widest scalar type between MAX(sizeof(long),
sizeof(void *)) is necessary, too. E.g. in libiberty there are such
cases I remember.
