Why doncha just use EMX 0.9a?  It's another GCC port so it's basically 
the same as DJGPP.  Except it can compile for BOTH native OS/2 and DOS 
(the same EXE can run either under OS/2 or DOS).  There's a catch 'tho 
... programs compiled with EMX can't run in a DOS VDM because it uses a 
DOS extender that uses the VCPI specification.  If you want to run an EMX 
compiled app under DOS, you have to run it under plain DOS.

There is, however, a DPMI compliant DOS extender for EMX called RSX.  
However, from I hear it performance under a DOS VDM is not all that 
good.  That's from what I hear ... I have yet to see for myself.

Anyways ... going back to original question ... I think you can run DJGPP 
in a DOS VDM without any problems.  I was talking to somebody about this 
just the other day.  The guy I was talking to did mention that there is a 
"quirk" with the DJGPP GO32 extender in a DOS VDM.  I can't remember what 
it was 'tho.
