OK, I'm sorry about that, but before I go into that, it seems as though
this problem is only hit by users of Acorn Risc PCs.

The difference is that the J and K versions of the SA-110 has a bug
that produces all kinds of weird problems. One of them is that cc
gives an internal error for no apparent reason.

I don't remember the bug in detail, but that was described in this mailing
list some time ago. You can probably find the articles in the mailing
list archive, or by using Olly's search engine at:
http://noxious.muscat.co.uk/riscbsd/

The point is that this bug has been fixed in the S and T versions of
the SA-110.

You can figure out if you have a buggy version by doing one of the
following:
1) Check the physical chip and see which letter is written after
   SA-110.
2) Boot a recent kernel and see if it claims that you have a buggy
   SA-110 in the boot message.

At present there is no workaround in NetBSD for this problem, and
none is planned for the forseeable future. The only option therefore
is to replace the chip or use the old ARM610 or ARM710 boards in
the Risc PC.

The 233 MHz SA-110s from Acorn seems to be at least version S.

I hope this clears up the confusion.
