Mmx is not supported though there is a -mpentiumpro or a m-i686 switch, I

Use the -march=pentium switch. That should work. Else, your GFX card is
the bottle-neck.
Oh, and please read the info about gcc.
Type 'info gcc' and then go look for compiler options, code generation
options, and look for i386. You'l find all the information you need.
