This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the address@hidden mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':


bug-cc-mode seems to be dead, so I send here instead.

It always annoyed me that add-log always put objc-methods as "-".
Internally add-log uses c-defun-name, so I'd like that defun to be
changed so it recognizes objc-names.  I have run with this for a while,
it handles all cases I've seen, but I'm sure some constructs make it
fail.  At least it is better than returning "-".
