State-Changed-Why:
    Hm, with 3.3 and present mainline, we get on this code
    -----------------------
    struct s {
        int x;
        struct { int x; };
    };
    ------------------
    the following message:
    g/x> /home/bangerth/bin/gcc-3.4-pre/bin/gcc -W -Wall -std=c99 -c x.c
    x.c:3: warning: declaration does not declare anything
    
    gcc3.2 is quiet. If compiled in C++ mode, we get this:
    g/x> /home/bangerth/bin/gcc-3.4-pre/bin/gcc -W -Wall -c x.cc
    x.cc:3: error: declaration of `int s::<anonymous struct>::x'
    x.cc:2: error: conflicts with previous declaration `int s::x'
    x.cc:3: error: duplicate member `s::<anonymous struct>::x'
    
    Joseph, is this approximately what you wanted gcc to
    tell us?
    
    W.
