I recall hearing that someone out there was working on it, but have heard
nothing about it lately.

I would think it's possible.  What you'd have to do is make it conform to
the OS-9 way of doing things.  Most importantly, that means generating
position-independent and re-entrant code.  If, in addition, you want to
roll your own cio, you'd have to make it conform to the Microware C
compiler's parameter passing conventions and notion that a6 points at
the process's data area (unless you want to make a rather major switchover
and get rid of any programs compiled using Microware's compiler--possible,
but you would be cutting yourself off from the rest of the OS-9 world for
almost anything you didn't have C source code for.)
