Hi Mark. Thanks for your reply.

The file window-NT/config.h defines DEVNULL as "nul" which is the
expected Windows NT localtion for a file with no bytes. The UNIX systems

So, I think you may take that there is nothing wrong with your output as

Even though "nul" is used internally by Windows
for a file with no bytes, surely the actual output
diff should have /dev/null in it for use on remote
systems that may not be running Windows?

Isn't /dev/null standard for diff files?

Certainly in 2011 whatever version of CVS I was
using (for Windows) was outputting /dev/null.

Note CVS 1.11.9 is very old (came out in 2003). You may wish to upgrade
to at least CVS 1.11.23 which was released on May 7, 2008.

You may find it useful to consider CVS 1.12.13 as the most recent
release of CVS provided to the net.

1.12.13 is dated 2005, so older than 1.11.23.

I will probably be porting CVS to PDOS/386 in the future,
so will upgrade as part of that.

BFN. Paul.
