Here, I think the multiply will be performed using signed int (in 
the common case that int is larger than 16 bits), or signed long 
(in the case that both int and short are 16 bits).  I can't see a 
case where unsigned int would be used, but I could easily be wrong 
-- this stuff is confusing.

I think it's much better to use explicit fixed-width types.
