sti is just working, IIRC

there's nothing wrong with the UW-SCSI to my knowledge.

There are still bugs.

>(compared to HP's cc, is there a significant performance difference) ?

in general, comparing gcc to a manufacturers compiler; there is
such a difference.

I can only say that compiling a kernel on my C200 takes about 2 times
as long as on my alpha (21164, 500 Mhz, 2 Mb cache). I feel it should
be faster.

Good luck,
