Subject: [Bug c++/18698] New: [3.4/4.0 regression] Error message using "using" for code not using "using" ;-)

The following invalid code snippet causes a strange error message:

===================================
template<int> struct A
{
    ::A~();
};
===================================

  bug.cc:3: error: using-declaration for non-member at class scope
                   ^^^^^^^^^^^^^^^^^
  bug.cc:3: error: expected ';' before '~' token

This was introduced in gcc 3.4.0. With gcc 3.3.5 I get

  bug.cc:3: error: invalid use of template-name 'A' in a declarator
  bug.cc:3: error: syntax error before `~' token

which makes more sense.
