Paul,

I just checkout from CVS repository and encountered the following problem
while building the code.

It seems you eleminate your original arguments of function gen_op_divs and
gen_op_divu.

Could you take a look?

gcc -Wall -O2 -g -fno-strict-aliasing -I. -I..

I would remember that if researchers were not ambitious
probably today we haven't the technology we are using!
