I'd personally love an option for make world to use egcs installed
from the port tree. And perhaps a new mailing list just for throwing
random egcs complaints at. Right now I'm manually building the source
tree with egcs to see how I fair. Any failures I get from building thus
far are replicable with the built in gcc, so egcs doesn't seem to choke on
the code all too much.
The kernel code is a slightly different matter. I get the
following errors:

Fun fun fun :-)
I built those two files with gcc and rebooted with the output.
Seemed fine.
