 The compatibility overload of call_once with reversed argument order leads
 to confusing error messages in clang.

 The reason is that clang tries to instantiate
 template<typename Function>
 inline void call_once(Function func,once_flag& flag)
 with Function = boost::once_flag.

 Could that overload be removed for the next BOOST_THREAD_VERSION? That
 would also help with codebases which need to use boost::call_once and
 std::call_once interchangeably as this overload is not present in the std
