Oh, wait, belay that. If we do that, we will be retroactively breaking
the no-working-64-bit-integer-type support in the older branches.
Probably not a good thing to do in minor releases. I guess we'll just
have to wait and see if any problems get reported. I can't see going
to the effort of making the new tzcode stuff behave gracefully without
int64.
