[Bug c++/42218] New: [4.5 Regression] Broken diagnostic: 'tree_vec' not supported by pp_c_expression

[reichelt at gcc dot gnu dot org]

A broken diagnostic is issued for the following invalid code snippet on trunk:

================================
template<int> struct A
{
  template<int> struct B;
};

int i = A<0>::B<0>::X::Y;
================================

bug.cc:6:21: error: 'A<0>::B<#'tree_vec' not supported by pp_c_expression#,
#'tree_vec' not supported by pp_c_expression#>::X' has not been declared

GCC 4.3.x and 4.4.x issue a sensible error message:

bug.cc:6: error: 'A::B::X' has not been declared

GCC 4.2.x issues an even better error message:

bug.cc:6: error: 'struct A<0>::B<0>::X' has not been declared
