Hmmm, the pseudo-ops are not affected when adding _CYGWIN__ to the #ifdef, these definitions like it is done for EMX are only important for the missing leading underscores (in case you get linking errors after compilation succeeded). You need to remove the pseudo-ops to get it compiled with MMX support.
