Is this a good idea? I thought some versions of gcc used long long for 128 bit integers, in which case int-ll64.h will give the wrong types for u64 and s64. I think gcc is changing to use the __int128 type, so this may be historical, but someone would need to validate that we have no architectures with the old long long behaviour.
