If you want to test the patch, here's how to go about it:
(i) Make sure you've got the program `patch' installed - it's in package
"diffutils".  (I don't know the package manager in Ubuntu).

(ii) Extract my email containing the patch to a file, say foo.diff.  You
don't need to bother separating out the actual patch from all the other
stuff.

(iii) Locate cc-engine.el.  It will be somewhere like
/usr/local/share/emacs/24.2/lisp/progmodes/cc-engine.el.gz if you
installed Emacs from source, or
/usr/share/emacs/24.2/lisp/progmodes/cc-engine.el.gz if you installed
Emacs from a package manager.  In either case you can find it for sure with
C-h f c-mode <ret>, and click/type CR on the file name.  Then do C-x C-v
to see where it is.

(iv) Unzip the source file: cd <above directory>; gunzip cc-engine.el.gz

(v) Patch that file: patch < /path/to/foo.diff

(vi) Byte compile the file: (in emacs)
M-x byte-compile-file <ret> /path/to/cc-engine.el

(vii) Load the file (or restart Emacs):
M-x load-file /path/to/cc-engine.elc
(note the 'c' at the end of ".elc")

(viii) Advisable: gunzip, byte compile, and load cc-cmds.el.gz too.
This is because it uses the "defsubst" (inline function) changed in
cc-engine.el.
