On this case, there is no behavior to be unified. The semantics that you
attribute to C-c C-c do not apply to CC-Mode.

What I can say about C++ is that, nowadays, CC-Mode doesn't recognize
language keywords, not to mention proper fontification and indentation.
Not even for post-C++11 features, but for C++98 as well (at least the
fontification part).

I could mail-bomb the CC-Mode maintainer with bugs and feature requests,
but I wont because it is totally unreasonable to expect from a volunteer
working on his free time to do a job that require teams of especialists
working full time for years.

Lisp, of course :-)

And, just to mention a modern language, Clojure. But that's cheating :-)
