I really can't figure why the kernel won't compile. (Other than the obvious
reason.)
If you're using gcc 3.2, the -msse2 flag is known to cause this problem.
Other than
that, what you propose sounds like the next thing to check.
I'll cc -questions, which is the proper list for tech. advice. Maybe someone
there
will have a better answer for you.
You can alter /etc/make.conf to change the flags; I'm not sure how it picks
up the
'automatic settings.' (Again, maybe someone at -questions will have a better
answer.)
Peace,
Clayton
