met/mediatomb fails to compile with clang++36. Works fine with gcc++ and
older versions of clang++.

The macro in question is:
#define SINGLETON_MUTEX(klass, recursive) template <> zmm::Ref<Mutex>
Singleton<klass>::mutex = zmm::Ref<Mutex>(new Mutex(recursive))
//template <class T> zmm::Ref<Mutex> Singleton<T>::mutex =
zmm::Ref<Mutex>(new Mutex());
template <class T> zmm::Ref<T> Singleton<T>::instance = nil;
template <class T> bool Singleton<T>::singletonActive = true;
Is this a problem with the code or the compiler? If it is the code, any
suggestions on fixing it? I have no clue about C++, but I'd really like to
get this working on HEAD.
