Ah, I wondered about that syntax.  We now initialize the pthread_mutex_t member
like so:

mutex() : _M_mutex(PTHREAD_MUTEX_INIT) { }

which is not portable.  We could add config checks to determine where the INIT
macro is valid, and for some platforms we could use:

mutex() : _M_mutex PTHREAD_MUTEX_INIT { }

But the ideal solution is to get brace-or-equal-initializers implemented for
non-static class members, then we can do:

native_type _M_mutex = PTHREAD_MUTEX_INIT;
mutex() { }
