I have had the same idea.  There are several problems that I can
identify.  It may be that all you need to do to the machine description
is to delete the 80386 commands that are not present in the 8086, but I
am not certain.  It would be necessary to provide your own run-time
library.  You would need a linker that generates an .exe executable
file, since the Unix format would not work.

I think this project is achievable, but is not a simple matter.  It
would be interesting to try to compile gcc into 8086 code, resulting in
a native gcc compiler for messy-Dos.  -David-
