The only thing -g should do is enable debugging symbols; it doesn't
generally have an effect on optimization.  Perhaps you mean -O0?

No, I think more likely -dgl- was talking about "the old days", when,
yes, -g did indeed kill the optimizer.  It's been a while, but there
was such a time.

...back when the dinosaurs roamed the earth, and computers had front panels
with switches and lights.

Thus sayeth the Old Guys. ;->

If anyone can give me some confidence in what switches I need to use to
get what we need, I can do the experiment(s).

- -mno-altivec or -mcpu=750 ( or anything else that's not a g4 or g5 )
That doesn't keep libc from running altivec code though.

have fun
