True enough.  Various things I have tried (such as the MAME drivers, parts
of DOSEMU, parts of the linux kernel) have produced both smaller and
faster code with -m386 and -O2 rather than -m486 and -O3.  And other
mixes.  This may not be the case with a Pentium.  I am using a Cyrix
6x86/PR120+ and it seems to ignore a lot of the rules for making code fast
on a pentium.  :)
