Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs <at> gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

It seems that emacs doesn't recognize the vc-status of the file when I
set the variable vc-rcs-checkin-switches to "-l". The first time I
execute vc-next-action for checking in the file is checked in and then
checked out automatically because of the "-l" switch. The %% are not
present in the mode line. The second time I run vc-next-action it
attempts to run co instead of ci. On the other hand, running
vc-next-action through vc-dir doesn't seem to have a problem. I only
observed this in emacs 23; emacs 22 is also working as expected.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
c:/emacs/etc/DEBUG for instructions.

I think that if you want to add -l to vc-rcs-checkin-switches, you also
need to do 

rcs -U 

on all your RCS files.  That way things are consistent and VC can figure
out what to do.

Hello,

Thank you for your reply. Based on what you said I was able to fix the 
error by applying the setting below, although I am not sure if that's 
the best solution. Thanks.

(setq vc-checkin-hook
     '(lambda()
        (if (and (buffer-file-name) (eq (vc-backend 
(file-name-nondirectory buffer-file-name)) 'RCS))
            (shell-command (concat "rcs -U \"" (file-name-nondirectory 
buffer-file-name) "\"") "*vc*"))))

Good, closing this bug then.
