Another person replied to this already, but I'll just toss out that instead
of using a pragma, this warning can (portably?) be removed by appropriate
casting. This should be fine since, obviously, this is the intended behaviour.
The pragma is simply a stop-gap measure that gets rid of the warnings
without forcing a lot of code modification.

Well, you can cast it to get rid of the problem...but (I don't have the
code with me, so this is conjecture), I assume you could just return ~0L
and the caller could check for that? I'm not sure what returning an
"unsigned -1" is really trying to do in this case.
