There is basically no chance that GCC will run native on a 16-bit
machine.  It likes large, contiguous data structures, which Intel
machines hate.  At least once the Microsoft/AT&T/Interactive
application binary standard for 8086 is finalized and adopted (maybe a
few years from now, when nobody will care any more), you'll be able to
buy Microsoft's MSC for Xenix and run it on Microport's Unix.

However, on the gcc front, I heard that someone is doing a 386 port,
and it should be possible to use that on microport unix on a 386 box.
It should be easy to bring up (once the 386 code generator is released)
if either:

     *	your current compiler can handle gcc's source (sounds like 
	microport's is unlikely to),

or   *	you have a real working Unix box, that gcc runs on, handy.
	You can cross-compile to 386 assembler source, move that
	to the 386 box, and assemble and link it there.  Then use that
	binary to recompile its own sources.  Once you've bootstrapped,
	you *have* a compiler that can handle gcc...

Watch comp.emacs, or get on the info-gcc mailing list by sending mail
to gnu at prep.ai.mit.edu, to find out when the 386 gcc comes out.
