I don't think I fully understand the closure of this bug. I understand if by
i686 you really mean Pentium Pro. (I hope that's documented.) The claim that
it would be dumb for GCC to generate code which checks for CMOV before using
it also makes sense. However, if there were a way to tell GCC not to
generate CMOV instructions in the first place, that would seem reasonable,
too, assuming there are other i686 optimizations worth doing.
