My -current trashbox is having some pretty severe problems which seem to
stem from the token ring additions on March 10th. The box in question
wouldn't stay up for more than a few minutes.
``savecore'' isn't working for me right now, but I've managed to delete a
single line of code which lets the box stay up long enough for me to do a
make world and get to grips with all this EGCS, uh, fun. This isn't a true
solution, obviously.
The ethernet segment to which the box is connected has lots of non-IP traffic
(DECNET, Novell, etc), but I didn't expect to find token ring stuff on it. :-)
Ian.
