State-Changed-Why:
    True, still happens with 3.3CVS. Maybe it would be possibly
    to identify the position of the token right before the
    point where we give the error, i.e. when the output
    (as in this example) is
    tmp/g> /home/bangerth/bin/gcc-3.3-pre/bin/c++ x.cc
    In file included from /usr/include/stdlib.h:33,
                     from x.cc:2:
    /home/bangerth/bin/gcc-3.3-pre/lib/gcc-lib/i686-pc-linux-gnu/3.3/include/stddef.h:213: error: syntax
       error before `typedef'
    
    then also output the position of the token before the 
    "typedef" token, at least if it is in another file.
