emacs 的 C++11 模式或设置?

I'm running Emacs 23.3.1 (Ubuntu, Oneiric package) and emacs doesn't appear to understand any of the new C++11 keywords, constexpr, thread_local, etc. Also it doesn't understand that '>>' is now permitted in template parameters, or the new 'enum class' syntax. Is there an updated or alternative module somewhere? Or failing that, some settings to make emacs more C++11 friendly in the mean time?

I've checked trunk version, cc-mode hasn't been updated yet, and AFAIK there's no alternative. If you really want it, but don't want to get your hands dirty, you should pay someone to implement it for you...
