Longs might be slow too.  Use [unsigned] ints.

I've seen reports that shorts (and chars?) are even slower (relatively)
on the P6.  I don't know why that would be - I would have thought that
movsx and movzx were near the top of the list of things to optimize
after the 486 optimized more important operations.
