This is _exactly_ your problem: DJGPP programs cannot access long file
names on NT, so you should have _not_ unzipped with long file name
support.  The name of the `progmodes' directory exceeds the DOS 8+3
limits, so Emacs cannot find it.

That's an illusion.  You just didn't see the problems yet.

This is unrelated to the problem I mentioned above: Windows _always_
passes files to DOS programs in their 8+3 short form, when you click
on the file name or drag-n-drop the file onto the DOS program.  This
happens even on Windows 9X, where DJGPP does support long file names.
A kind of welcome party from uncle Bill, I'd say.

This is again because DJGPP programs cannot access long file names on
NT.

Because you unzipped it with a DOS unzip program, probably.  Or maybe
that was a Windows port of Emacs, not a DJGPP port.
