Hmm, i thought i've already fixed (or hidden :) all of them...  Obviously,
i only posted the fix here, but never got any feedback.  The signed/unsigned
warnings have the problem that we'd need more of the combined mul/div
functions in order to cover all possible combinations of signed/unsigned
non-long/long argument pairs in order to properly handle them.
