title: C++11 mode or settings for emacs?
body: <p>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?</p>
