one major problem is that dosemu uses V86 mode.

My personal, and very satisfactory, solution to this problem is as
follows. I develop under Linux and use the SUIT library to great my GUI.
This allows me to use all the usual UNIX tools etc. As SUIT has been
ported to DJGPP/GRX, my programs can simply be recompiled under
DOS/DJGPP for use on a PC - WITHOUT ANY CHANGES TO THE SOURCE CODE !
(Of course I can't use signals, fork() etc...)
