State-Changed-Why:
    I tried your program with gcc3.2, but on x86 linux. I can 
    confirm that the mentioned symbols are present in the 
    object file. However, they are weak:
    00000000 W std::string& std::string::_M_replace<....
    
    Weak symbols means: they can be in multiple object files,
    and one of these copies is picked at link time.
    
    Could you possibly check whether the problem still exists
    on your platform with gcc3.2.1?
    
    Thanks
      Wolfgang
