I did a `make world' yesterday with
CFLAGS= -O2 -pipe -march=pentium
COPTFLAGS= -O2 -pipe -march=pentium
(inspired by recent mention of optimizing on this list) on my
AMD-K6(tm) 3D processor (350.80-MHz 586-class CPU)
desktop machine. It still runs, but I'll have yet to see whether
this will cause any suspicious behaviour.
If it doesn't I'll probably try `-03 -pipe -march=pentium' come next
`make world' time, but this all is about a machine that has it's
backup mechanisms (hopefully) and can afford a little downtime.
