I am, however not referring to porting to A/UX, but rather both the
Macintosh environment, and the MacBSD environment.
As far as patching source, in general one can consider this to be de
riguer for such a project, and hence beneath comment.
I do find that I do less source patching with NetBSD than I do with
SunOS these days for many modern sources, especially if I am porting
something either strictly ANSI, or for a POSIX compliant environment.
As long as you can _get_ NetBSD running on a Mac, you can get gcc
running on the same machine, and hence, you can build gcc on it. The
work is there with any port.

It does not compile straight out of the "box" for the Amiga either, but
it can be done by someone willing to take the time. And if you can
build one pass, you can build the next. Eventually, you have a compiler
which will work with anything.

Same thing with the Amiga: m68k-commodore architecture not supported.
It has been done anyway. I had a cross compiler up under 2.5.7 that
could have been made to build for MacBSD with minimal modification.
If someone will ftp me a recent working libc for MacBSD, and source
for same, I will build a sparc cross compiler.
Easy is not something that fits into the arena of an FD Operating
System, easy is getting a commercial product and bitching because
you do not have the source code to make it do your will.
We should probably keep this off of this list, unless the majority wish
to discuss it.
