I agree we should go to -O2 default
I was building cvs version of gstreamer-plugins earlier with -O 
-march=athlon-xp -pipe plus the fix we have in gstreamer-plugins in 
ports now
and gst-register core dumps, but it works with -O2. So I'd imagine 
we'll just run in to more problems in the
future.

in the long run I think -O2 is the best bet for at least OSVERSION > 
50000 (or all versions)
I don't think this is a problem with gcc2.95 because it doesn't have 
march=athlon-xp or p4.
But I have done very little testing other than march=pentiumpro on 
gcc2.95
