Hmm, I've got a stock 2.0.33 working with the current 1.0.2 prerelease
sources with the following options for my two x86 boxes:
"-O2 -fomit-frame-pointer -mcpu=pentium -march=pentium"
"-O2 -fomit-frame-pointer -mcpu=pentiumpro -march=pentiumpro"

I didn't configure for haifa, and I also don't have 3c59x configured
into my kernel (cuz I don't have a vortex :-)

We're closing in on an egcs-1.0.2 release, and I'd like to nail down
any problems of this nature asap. What can I do to help y'all
nail this problem down?
