Tom,

Here's the sources that I've used and abused for this version of
MicroEmacs.  The new stuff is in c/qnx4.c, and I've separated out
the spawning etc. code from the Unix code into c/posix.c, though
just how POSIX compliant it is I'm not sure.

Enjoy yourself with it.  If you feel inclined, forward it off to
Quantum to put onto QUICS.

Jim
