Heh.  Most of those messages were probably from me desperately seeking
assistance of any kind (quick check confirms this).  :)

I do not have another machine I can use to test on, unfortunately.  Upon
attempting to buildkernel a couple more times today, I get the exact
same ICE in the exact same place on the exact same snippet of code.  I'm

I haven't been running cvsup -s.  I just run the command line 'cvsup -g
-L 2 source' (source being the name of my sup file).  I'm currently
installing the gcc33 package to see if this alleviates any of my

I was also wondering if there was a way to build the system with an
older compiler (like, say, 3.1)?  I had these same problems with 3.2.1
so I wondered if going back to an earlier version would eliminate the
