Present mainline after the merge of the new parser
>Description:
This code (note the missing "typename" keyword)
-----------------------------template <int dim> struct O {
    struct I {};
};

template <int dim> void f() {
  new O<dim>::I();
};

template void f<1> ();
-----------------------------
makes present CVS (with the new parser) issue
  tmp/g> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -o /dev/null -c bug1.cc
  bug1.cc: In function `void f()':
  bug1.cc:6: error: expected type-name
  bug1.cc:6: error: expected type-name
Note the duplicate message. I have another small grieve with
the message, since the line of course contains a type-name,
but what is really missing is a "typename", i.e. hyphen
or not. The old parser issued this:
  tmp/g> /home/bangerth/bin/gcc-3.3-pre/bin/c++ -o /dev/null -c bug1.cc
  bug1.cc: In function `void f()':
  bug1.cc:6: warning: `O<dim>::I' is implicitly a typename
  bug1.cc:6: warning: implicit typename is deprecated, please see the
     documentation for details
This is more explicit, and would help people who don't
understand the typename-business more.

In any case, both these issues are really minor points, so
I lower the priority.
