Makes sense, i686 is used for PPro,P2 (and above) and Athlon.
Winchip is definitly not in their class :)
Cyrix III (which for all intents is a Winchip) should be another

*nod* would make sense.
I can't remember if it was me that made this change or not, if so
I'll wear the bag this time :)
I actually thought that the i686 target was the same as the i586 target
with different instruction scheduling rules. Seems my judgement was off.

Looks okay to me.
This isn't an issue on 2.2.x as we don't have the Winchip target there.
Good work :)
