Okay, I've done another pull and rebuilt xenolinux 1.2 with both gcc 2.95.4 and gcc 3.0. Both of these boot dom0 and find hda just fine. The only thing that's changed is the code changed by the pull. (Note that I'm talking about xenolinux only here -- I'm still using the gcc 3.0 Xen -- haven't tried Xen with gcc 2.95 since I hit those parsing errors on Thursday.)

I suspect this was in fact the culprit -- possibly I grabbed the code when it was in an intermediate state (Thursday evening Pacific time). > Anyway, that's just for info -- I believe it's fixed now, right? We can call this fixed. Thanks everyone for your help. Steve -- Stephen G.
