Synopsis: missing definitions for <?= and >?=

State-Changed-Why:
    This is probably a corner case whether I should close the
    report: this has never worked (used to ICE)
    ---------------------------------
    class C {};
    C operator <?= (C) { return C(); }
    --------------------------------------
    I don't think it was ever documented that one should be
    able to overload this operator (a gcc extension anyway).
    Now we at least get a reasonable error:
    g/a> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc
    x.cc:2: error: expected identifier
    x.cc:2: error: expected type-name
    x.cc:2: error: expected `,' or `;'
    
    So the fact that the new parser rejects the code is ok, and
    is not removing a documented extension.
