Your problem is simply a basic incompatibility in the DPMI spec.  You
cannot mix 16- and 32-bit DPMI applications under the same host, period.
It's just not possible.  The only solution to your problem that I can
think of is to find a real-mode DOS port of make (like Borland Make)
and use it for your compilation instead.

I don't know why that particular command line bombs emacs, unless it's
something to do with the way abmake handles memory.

Probably won't help, but go ahead. :)
