I think the only optimization gcc 2.7.* does for i486 is instruction
alignment. The Pentium has a better fetch unit so doesn't need any
alignment (it never incurs a misfetch penalty) so optimizing for i486
will at least give some code bloat.
I don't think it does any optimization at all for pentium.
