Oh, ok, that makes it even easier to say this with certainty:
Changing the other 64-bit archs to use "long long" for their 64-bit
numbers will not cause additional warnings. I'm also almost certain
there are no architectures which use "long long" for 128-bit
integers. (Moreover, I can't find hardly anything which does 128-bit
integers at all).

Cheers,
