The gnu compiler does need them (there's no C/C++ expression which might
result in a MMX instruction). The assembler, I thought it already did,
but I may be mistaken since the assembler primary is used as the
compiler output translator. Adding library interface functions would
require emulation to be written for those not having MMX (like most of
us do (and don't know)), and that has not been done.
NASM supports them!
