That is incorrect.  All DJGPP programs are 32-bit programs.  What makes
you think your DJGPP-compiled program is 16-bits?

DOS4GW is a Watcom extender for Watcom programs  (though I'm sure any
program with the proper interface can use it).  DJGPP uses DPMI to
provide 32-bit services to its programs, and does so transparently to
the program; meaning that the programmer doesn't have to do anything
special to use it.  The generated code does it automatically when it's
necessary at all.  Windows 3.1 has a DPMI server built into the system
already, so you don't need to do anything if running DJGPP-compiled
programs in a DOS box under Win 3.1 (or Win95 if you decide to go that
route).  If you run from straight DOS, you'll need a DMPI server
(CWSDPMI is the DJGPP default standard, and is free for the taking).

You don't need it, and DJGPP won't use it.
