This problem is explained in the file etc/PROBLEMS:

    *** When compiling with DJGPP on MS-Windows NT, "config msdos" fails.

    If the error message is "VDM has been already loaded", this is because
    Windows has a program called `redir.exe' that is incompatible with a
    program by the same name supplied with DJGPP, which is used by
    config.bat.  To resolve this, move the DJGPP's `bin' subdirectory to
    the front of your PATH environment variable.

That is very strange: building an official release should not require
a bootstrap.  Did you build the official emacs-22.3.tar.gz
distribution, or did you get your sources in some other way?  Did you
perhaps delete all the *.elc files somehow, e.g. by running Make with
some target that cleans too much?

This happens because you either don't have the DJGPP port of GNU Find
program, or again because the Windows find.exe (a totally different
program) is found on PATH before the GNU find.exe.

This is the consequence of the previous problem.

Btw, Emacs 22.x has several bugs in the DJGPP build, so I encourage
you to try the CVS version of the upcoming Emacs 23, where these
problems are resolved.

That's strange.  I suspect something went wrong when unpacking the
distro, or perhaps you inadvertently deleted all *.elc files in one of
your previous attempts.

I don't think I tried a full bootstrap in Emacs 22.x for a long time;
it's possible that something broke since I last did.  The DJGPP build
of Emacs 22 was not maintained for several years, so it's quite
possible that it bit-rotted.

That's a known problem in Emacs 22.3; it is corrected in the
development sources for the upcoming Emacs 23 release.  To fix this in
Emacs 22.3, apply the patch below, then byte-compile startup.el and
say "make install" in the top-level directory to rebuild Emacs.

(In case you didn't know, to byte-compile startup.el, chdir to the
`lisp' subdirectory and type "make startup.elc".)

If you mean this last line, then it's harmless (cmd.exe does not
support the trick of detecting whether a directory exists by checking
if a ``file'' named NUL exists in it).  Just ignore that error
message.

When is this error message shown? when you click on [State]?  Also,
what is your HOME environment variable set to?  Please give me a
complete recipe for reproducing this, so I could see how to fix it.

You can always save them manually, by editing .emacs yourself, until I
find the problem and fix it.

I think this is due to some messup with your user name as Emacs sees
it in your setup.  Please tell me what these two commands print:

  M-: (user-login-name) RET
  M-: (user-real-login-name) RET

That is the reason: the two should be identical to avoid the problem.
Does it help to define the environment variable LOGNAME whose value is
the same as the Windows user name, before starting Emacs?

This won't necessarily help, since user-real-login-name might be nil
(not yet initialized) when Emacs processes that line in your .emacs.
Setting LOGNAME in the environment should solve the problem in a more
consistent and predictable way.

Sorry, that was wrong.  (It's been a while since I researched this
problem, so I forgot the details.)  You need to make sure both USER
and USERNAME environment variables are set to the same value.  Windows
sets USERNAME, so if you want to keep that, make sure USER is set to
the same value.  If you don't want to set USER globally, you can do it
in the [emacs] section of your djgpp.env file.

Again, I should have said "setting USER".

I added a description of this problem and its solution to etc/PROBLEMS

Thanks for helping me find and diagnose this.
