OK. That makes sense that "long" is 32 bits on a 32-bit CPU.

Yup, that's the question: could we change that "long" to int64_t or uint64_t
and would that break other parts of the code and what would it do to platform
portability?  I can make either of those changes on my system and still
pass "make check", but I don't know how it would impact other platforms.
