If you are using the Cygwin build of RCS with a native build of Emacs,
there could be problems that I'm not aware of.  I don't use Cygwin.

The native Windows port I found on the GnuWin32 site.

That is already a sign of a problem.  The buffer should be read-only.

What does "rlog test.tex" show after that initial checkin?

What does user-login-name and user-real-login-name return inside
Emacs?
