	First of all, I must say that I'm enjoying this discussion a
	lot and that although I never used this pentium-builder thing,
	I think that it's pretty slick.

	I guess that recompiling every package is not worth the
	trouble, but recompiling multimedia and CPU intensive ones may
	be a major gain (say, MPEG players and such).

	BTW, you can use -O6 for your programs. If I remember
	correctly, it will fallback to whatever is the highest mode of
	optimization (somebody please correct me if I'm wrong -- I
	read this a long time ago and didn't find it listed in the
	current documentation now; the funny thing is that it's not
	mentioned in the current potato manpage).

	I also don't know if -O6 does the same thing as -O9.


	[]s, Roger...
