I'm looking at it.  Non-trivial, Gcc isn't realy written in portable C
and some things needed or desirable for os9 arn't there yet.  It can
start as a cross-compiler or possibly a hacked preprocessor would be
enough for a first pass.  Getting the agument passing to match what
Microware C generates would be nice, but assebler stubs could be used
for the library interface.  The major thing after my quick look
through would be convincing gcc to generate memory references as
offsets of a6 rather than absolute.

The gcc compiler source is about 5 megabytes, not including needed
utilities like bison...

[Gcc is a free (but not public domain) optimising C compiler from
the Free Software Foundation, who put out GNU Emacs and are working
on the GNU operating system.]
