I don't use assembler, it is just in plain ANSI-C. The good thing is
that allows me to change compilers with no change in the code whatsoever and
that is what I did.
Maybe the MVSC uses some of those instructions when chew up my sources and
gcc don't?

The weird thing is that K6-2 is not slow _if_ I use gcc. With the rest of
the machines MVSC is better...
