    This is a regression -- sort of, because I do not know
    whether it is legal: starting with gcc3.[12].*, this code
    is rejected:
    class a {
        __attribute__((section("whatever"))) a();
    The message I get is this:
    tmp/g> /home/bangerth/bin/gcc-3.3y-pre/bin/c++ -c x.cc
    x.cc:3: warning: `section' attribute ignored
    x.cc:3: error: declaration does not declare anything
    x.cc:3: error: parse error before `)' token
    Now, what is indeed surprising is that this only happens
    for the constructor. It compiles just fine if the attribute
    is applied to a normal member function.
    On the other hand, if I place the attribute specification
    _after_ the constructor declaration, then it works, so
    maybe it compiled "by accident" before. It is inconsistent,
    Since this is a change, I place this report into "high"
    priority, so that at least someone will clarify the situation.
