State-Changed-Why:
    Confirmed. The problem comes from code like this, buried deep
    inside libstdc++:
    --------------------
    struct pthread_mutex_st {
        void * res0;
        int res1;
        int res2;
        int res3;
        int res4;
        int res5;
    };
    struct pthread_mutexattr_st;
    //...
    typedef pthread_mutex_t __gthread_mutex_t;
    //...
          __gthread_mutex_t __tmp = {0, 0, 0, PTHREAD_MUTEX_TIMED_NP, { 0, 0 }};
    -----------------------
    
    This happens in bits/stl_threads.h:74, so I better
    reclassify it for libstdc++.
    
    Georg, in this case it would be interesting to have
    the original, unpreprocessed code, to see whether it
    works with newer and/or older versions of gcc. Can you
    provide a stripped down version of it?
    
    Thanks
      W.
