The Emacs debugging interface isn't supported in the DJGPP port, because
it requires asynchronous processes to work.  This is explained in the
MS-DOS chapter of the Emacs manual.

I don't know anything about GDB support in these versions of Emacs; I
suggest you post your question to the gnu.emacs.help news group where
such queries are appropriate.  However, even if you do get `M-x gud'
to work on those platforms, I doubt if you will be able to debug DJGPP
programs with them, because they probably work only with Win32 ports
of GDB, which doesn't support DJGPP.

If you need to debug DJGPP programs, you can use RHIDE or RHGDB; see
the DJGPP FAQ list (v2/faq210b.zip from the same place you get DJGPP)
for pointers to these packages and explanation of their features.
