OK, problem solved. My machine has a good gcc, but was still using
the SCO as that knows nothing about mmx apparently. The trick was
to get assembler using gcc -S, then generate a binary using the gnu as,
and finally to get an executable using gcc again.
The iteration count approximately doubles, from ~90K to ~160K,
so it was well worth the effort.
The gnu as comes in the binutils package. I tried forever to build
a new gcc but was not successful -- in the end only the as was needed.
Thanks to all who contributed tips!
