C-x C-f c:/test.txt RET
type some data and save with C-x C-s
C-x v v
Chose RCS as backend.
Notice that the buffer is not read-only, and the same goes for the file.
This is dangerous since I by mistake started to edit a file, thinking it
was checked out. When I then did C-x v v RCS checked out the previous
version on top of my working files, overwriting all my changes.
Thanks!

It works for me with the current trunk under GNU/Linux.
Either this is MS Windows-specific, or...

... that is fairly old. Please try the latest 24.0.9x pretest from

It works for me on Ubuntu GNU/Linux as well. I have tried to debug it and I haven't
been able to arrive at a conclusion (hence this bug report) myself, but I am pretty
sure it has to do with the fact that it runs under Windows. For some reason, vs-rcs
is not able to set the file read-only after a check in or "register file" operation, like
under GNU/Linux.
I think one of the more experienced Emacs developers who has access to Windows
Will be able to recreate and find the cause quite easily. For me, vs-rcs is a bit to...
messy to understand.
>... that is fairly old. Please try the latest 24.0.9x pretest from
Sorry for that. I do use a newer version but I happened to use the older version
for reporting the bug. I have the same problem with the pretest from the middle of
January.
Thanks for the prompt reply!

This rings a bell. Please see if this is not a duplicate of 8924.
You can find the RCS binaries I mentioned there on this page:

Eli's hunch was correct, it had to do with the RCS tool I used, which was from Cygwin. I installed the binaries Eli pointed to and made sure those were found earlier in the PATH and not it seems to work.
Also, I was a bit embarrassed when I understood that RCS was not an internal tool in Emacs... I don't know why, but I got the impression that Emacs was handling the RCS stuff internally, so I never suspected that there would be external tools.
Thanks!
