Here is a message I have just been able to send to the RCS developers.
Thought people on this list might be interested. Also, if anyone
(particularly with a newer version of DJGPP) wants to pick up my
changes and try them out, I'd be grateful.

> Subject: DOS/GCC port of RCS 5.6.4 beta
> To: rcs-bugs AT cs DOT purdue DOT edu
> 
> I have made what appears to be a successful port of RCS 5.6.4 beta
> (plus MSDOS files) to DOS using DJ Delorie's port of GCC. 
> 
> Took the 'rcs-5.6.4-beta.tar.Z' and 'msrcs-1.8-beta.tar.Z' files from
> ftp.cs.purdue.edu in pub/hammer. Modified the Unix 'Makefile' and the
> MS-DOS conf.h. Copied the logindos.c, getcwdsl.c and *.rsp files from
> the 'ms' directory. Compiled and it appears to work fine.
> 
> I have the DOS ports of the fileutils (ls, rm, etc.), and 'gnumake',
> as well as a /bin/sh clone, which made using the Unix Makefile much
> easier. System is a 386-40MHz, 4Mbyte RAM, 105Mbyte hard disk (IDE),
> MS-DOS 5. No guarantees on the quality of the port at the moment -
> getting the 'rcsvers.c' rules to work OK was a pain, and I don't think
> it is right yet (limitations in the /bin/sh clone, that I then tried
> to work round). Also, gnumake didn't seem to have its default rules
> mechanism working, so there are a lot of new rules at the end to build
> the .o files. I have also not been clean in using $x, $o extensions in
> the makefile and *.rsp files...
> 
> I had to comment out a number of things in the conf.h since they
> clashed with the definitions the gcc header files gave me. Note that I
> do not have the current version of DJGPP - I have 1.04 or so, and the
> current one is 1.09. DJGPP 1.04 is either a gcc 2.1x or 2.2x port. I
> simply iterated until I got a totally clean compile.
> 
> I have only done preliminary testing so far, but it appears to work
> OK.  Everything I have done so far has worked, though I want to check
> the write permissions after 'ci -u' again - I noticed files were
> (sometimes?) left writeable, but am not sure whether it is me, MS-DOS,
> or RCS... By the way, having the manual pages processed in the MS-DOS
> tar file was *extremely* useful - useable man pages on a PC!
> 
> I don't have a lot of time at present, but will be trying to clean up
> the port and check the functionality some more. In the meantime, my
> modified 'conf.h' and 'Makefile' files are available by anon.ftp. at
> ftp.epcc.ed.ac.uk in directory pub/rcs/dos_gcc.
