Hello Steven!

Sorry this answer took so long. I was off on a holiday in east Germany.
Now I have settled in again and got back to my old problems. :-)

I've been much more careful that you, as I have only added the mcpu-flag
and also added the mtune-flag (both set to ultrasparc). The -O2 I left
in place.

In many cases, things won't compile. This includes the world as well
(make buildworld). While I am writing this, I am running a csup on my
Sun, so I can try again with the current sources (RELENG_6).

Once again, it didn't work. :-( I only used the flags above in
/etc/make.conf and buildworld doesn't work anymore. Can you actually
build a whole world with those flags?

I'm putting the results (final lines) below.

make -j 2 buildworld starts here...
