For what it's worth, it doesn't seem to have quite reached that aim
yet. When I compile kernel 2.0.33 with gcc, it works fine.
When I compile the same kernel (same configuration, after executing
"make mrproper") with gcc 2.8.0, my X servers and certain other
programs dump core. I don't have detailed information yet, but it
appears that the programs are dumping core in routines that perform
I/O port access.

Has anyone else experienced this? Should I try to gather more
information on the problem?
