I've had enhancements for some C++11 features integrated into CC Mode at
SourceForge for some while, but I haven't yet pushed them to the
repository there (with one exception).

These features are:
(i) ">>" as double template ender (already at SourceForge);
(ii) "auto foo = <expression>;";
(iii) "decltype (foo)" as a type;
(iv) "auto foo (<args>) -> <type> { ..... }".

Daniel, in the end I didn't use the code in your patch, though the test
file was handy indeed.

I'd been hoping to implement more C++11 features before releasing all
the above, but I'm not getting much done.  I don't have enough time to
spend on CC Mode, and I'm largely bogged down with bug fixes at the
moment.  If somebody were willing to spend the time to learn how CC Mode
works, then implement more of C++11's features, I'd be most grateful for
the help.
