Hi
The -mmmx question I think is as Linus said: you have an old gcc
compiler which appeas not to support this option.
I also tried an AMD chip and the mmx code works. Your chip
capabilities confirms this listing "MMX".
The -mcpu=pentium just tells it to optimize for pentium (but code is
still runnable on 486s etc).
