Synopsis: access by friend function's default argument

State-Changed-From-To: feedback->analyzed
State-Changed-By: bangerth
State-Changed-When: Thu Oct 31 09:24:55 2002
State-Changed-Why:
    One way or other, the example Christoph gave shows a bug,
    since treatment is not consistent. So I reset the state
    to "analyzed".
    
    And no, I don't know what is right and wrong here, sorry.
