Synopsis: [2003-01-21] Using null pointers for fake addressof() generates warnings

State-Changed-Why:
    3.3 and present mainline say this:
    
    g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c 2810-2.ii
    <internal>:6: warning: invalid access to non-static data member `X::p' of NULL
       object
    <internal>:6: warning: (perhaps the `offsetof' macro was used incorrectly)
    
    I think the warning is valid, but if you don't like it you're
    of course free to shut it off.
