I agree the C++ standards should matter one bit to postgresql, but
AFAIK C99 also says "long long" is at least 64 bits too -- but if
we're talking C99, we'd be better off using whichever of int64_t
or int_least64_t or int_fast64_t we really meant anyway. Since we
don't I assume we're trying to be compatible with pre-c99 C too
which AFAICT means you can't assume much about "long long" either.
Pre-C99 you can't really count on much. I've spent time where "int"
was 20 bits; and on another platform where int was 32 bits and
long 40 bits.
