OK.  I suggest proceeding as follows.  First download the CC Mode
(Mercurial) repository, as detailed above.  Then get the diff between the
"default" branch (i.e. the trunk) and the c++11-0-1 branch for the files
cc-*.el:

    hg diff -r default:c++11-0-1 cc-*.el > foo.diff

.  Then (the hard part), disregarding the irrelevant diff hunks in that
file (e.g. changes in the copyright statement), apply the diffs to the
CC Mode files in the Emacs trunk.  This will likely involve a fair bit of
hand editing.  Please do this job very carefully - it would be a
knightmare to untangle if you were to make mistakes here.

Before committing this it would be best to test it using the regression
test suite in the directory ...../tests.  See the comments in the file
..../tests/000tests.el for instructions.  You'll need to move the entire
..../tests directory to under ..../lisp/progmodes (or set up appropriate
symbolic links) for this to work.

As a commit message, could you copy them from the CC Mode repository,
please.  All the commits in the c++-11-0-1 branch can be got reasonably
with:

    hg -v log -X .hgtags -b c++11-0-1

.  All the commits in default can similarly be got with

    hg -v log -X .hgtags -b default

.  Whatever changes are in c++-11-0-1 which aren't in default are the new
C++11 features.  They should form the basis of your commit message.

If you need any help, just email me.

Good luck!
