I was referring to the "untouched" assembler files, DJGPP's COFF sections are aligned to 16 bytes by default, so if you have the SSE data at the beginning of a section, it should work (for me it worked). IIRC HAVE_MMX failed because of the memalign problem I describe below. Personally I used #define memalign(a,b) memalign(b,a), and it finally worked.

You can also use DJGPP's memalign, but it takes reversed parameters comparing to the one from Linux.
