We (Omron Corporation) use the D.G. 88k port of gcc for our MACH 88k box.
From the same source we generate a local compiler and a cross compiler
(runs on our 68k BSD boxes -- produces code for the 88k machine).
Changes to get dbx debugging output can be minimal (as our ours),
but of course you've got to have an assembler, linker, debugger,
etc. that can deal with it.

The changes can also be pretty large if you want "vax-like" assembler
syntax.  There are groups in Sweeden in The States that have done this.

D.G. also is doing the gdb 88k port; that was much more difficult to port
to our MACH machine......

Contact Data General...  my contact is (I believe this is public info)
Tom Wood at uunet!rti!xyzzy!wood. I currently have version 1.37.23.
