State-Changed-Why:
    Reporter gave this example
    ----------------------
    template <class T>
    class A
    {
     public:
      static T * instance;
    };
    
    template <class T>
    T * A<T>::instance = 0;
    
    int main()
    {
      A<int> cB;
      cB.instance=(int*)1;
    }
    --------------------------
    It is supposedly not working on this platform.

State-Changed-Why:
    [HP-UX] 32-bit port doesn't support weak symbols and as a
    result template classes require explicit instantiation.
    
    The example will compile and run correctly if you add
    
      template class A<int>;
    
    For other examples, look at the instantiations in
    libstdc++-v3/src/*-inst.cc.
