Gcc will usually produce only one idiv instruction for n/d; n%d pairs 
for integer types smaller long long. It does in this case, when 
compiled with -O or -O2. There seems to be some redundant movs,
but it probably is not worth the trouble to avoid those. (Eric 
switched the two expressions, which produces slightly better code.)
