About 3 years ago, I managed to compile a then-current gcc on
a Luna-88k running Mach 2.6.  If I remember correctly, the
compiler was fine, but the assembler and possibly ld did not
work, but I was able to use the ones that came with Mach without
problems.
This hacked setup worked well enough to compile a NetBSD 1.3ish
kernel with all the machine dependent bits filled in with either
Mach code or stub routines.  (Of course it crashed after printing
a few things when I booted it...)
I should still have those binaries if they would be useful to
anyone.  Or, I might be able to put one of my machines on the net
as a build machine if that would be useful.
Not exactly "rock-solid", but its a start, I guess...

Excellent!  Thats about where I got stuck before.  I was trying
to use the Mach pmap.c, but it was very messy...
