[Bug c++/33210] New: Broken diagnostics: 'bound_template_template_parm' not supported by pp_cxx_unqualified_id/dump_decl

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following invalid code snippet triggers a broken diagnostic since GCC
3.4.2:

======================================================================
template<int> struct A;

template<template<typename> class B> A<B<int>::x> operator() ();
======================================================================

bug.cc:3: error: `A<#`bound_template_template_parm' not supported by
pp_cxx_unqualified_id#::x> operator()()' must be a nonstatic member function

A similar error message is generated by the following code snippet since
GCC 3.4.0:

======================================================================
template<template<typename> class T> void foo(int, T<int>::x);
======================================================================

bug.cc:1: error: `#`bound_template_template_parm' not supported by
dump_decl#<declaration error>::x' is not a type
bug.cc:1: error: ISO C++ forbids declaration of `parameter' with no type
