Yes.  Running on Solborne (Sparc) based system.

For that you may want to talk with some people in Buffalo.

No doubt about it.  You want to get the latest sources from Tom Wood at
Data General <wood@dg-rtp.dg.com>.  Tom, and before him, Mike Meissner,
have done a superb job getting GCC to be stable, robust, reliable, and
intensely ANSI conformant on the 88k.  They (and DG) deserve high praise
for this work, and for sharing it freely with 88k users.

If you get Tom's latest version, I'd be surprized if you had *any* problems
in terms of reliability.

That's trivial.  Just run:

	config.gcc m88kdgux

as if you were going to build it on an AViiON and then do :

	rm -f config.h
	ln -s config/xm-sparc.h config.h

Then make it.

GCC is very nearly as good as it gets on an 88k these days.
