Ok so I followed the Makefile convention and created a new Makefile for DJGPP
much like the others so that part is the same.

WATT32 needs to be placed in a directory with the same parent as binkd. I
build it myself and there are instructions on how to do so here
http://watt-32.net/

c:\src\binkd
c:\src\watt
           \lib
           \bin
           etc, etc,

I used the DJGPP 7.2.0 build from here
https://github.com/andrewwutw/build-djgpp/releases

As for a DOS environment I used MS-DOS on real hardware but I suspect a VM
would be fine. As for setting up a packet driver that is far too much to be
explained here since it depends on network card. There is enough information
abound on the internet about setting that up accordingly.

One caveat at the moment is the Makefile has directives to build for pentium
architectures and you might need to change it to suit your needs.

If I can help in any other way, ask away.
