I think that no one denies that with Vista DJGPP has reached the end
of the road on Microsoft operating systems.

Only for the record: with the 2.05 release it is possible to compile the
repository code without any difficulties.  On MSDOS-6.22 with DOSLFN 0.41c
it took around 7 hours.  On FreeDOS 1.0 (not FreeDOS 1.1) without LFN driver
it tooks 3:39 hours.

Every thing else will become really difficult due to different issues in
FreeDOS and other issues in certain DJGPP ports.  May be there are also
issues in libc.a itself.  I do not know if every code snippet committed
to the repository has really been checked to work on MS-DOS too instead.
I doubt that the vast majority of the developers still have access to
some MS-DOS version.
