This assumes that 16-bit platforms are not supported, of course.
It is a bit flaky anyhow and will need adjustments for possible
128-bit platforms. (I track some MLs, and i think on FreeBSD in
commit messages, or -hackers@, or -current@, i saw the one or the
other statement towards awareness of integer types and 128-bit.)
Maybe add another #if to check whether int itself is 64-bit.
