I envision a non-trivial effort doing that, an effort that is IMO a
waste of valuable resources.

The current DJGPP build "just works", given that you have a correct
setup on a system that supports the build (requirements for supporting
the build might be different from those for supporting running of the
binary).  I have built all the pretests of Emacs 24.4 with no
problems.  I have reports from people who successfully built the
previous version, 24.3.  The problems you saw on FreeDOS using the
current build system are either due to FreeDOS specific issues or to
your particular setup and the tools you installed.  We could try
debugging those problems, but unless you intend to continue building
the DJGPP port, that, too, would be a waste, IMO.

Given the above, investing efforts in moving DJGPP to the Posix
configury is a waste of resources that are best applied to parts of
Emacs that will benefit users of modern systems.

Again, if after all I've said, you still want to work on that, feel
free to do it, and thanks in advance.
