[Bug c++/16661] New: class-disambigued explicit c-tor call

["boris at kolpackov dot net" <gcc-bugzilla at gcc dot gnu dot org>]

$ cat >test.cxx
namespace n
{
  struct s
  {
    s (int i);
  };
  
  void
  s ();
  
  void
  f (struct s const&);
  
  struct s
  g ()
  {
    f (struct s (1));
    return struct s (1); 
  }
}

$ g++ --version
g++ (GCC) 3.4.1

$ g++ -c test.cxx
test.cxx: In function `n::s n::g()':
test.cxx:17: error: expected primary-expression before "struct"
test.cxx:18: error: expected primary-expression before "struct"
test.cxx:18: error: expected `;' before "struct"
test.cxx:18: error: expected primary-expression before "struct"
test.cxx:18: error: expected `;' before "struct"

Rewriting n::g () like this helps

struct s
g ()
{
  f ((struct s) (1));
  return (struct s) (1); 
}

Original example compiles fine with gcc 3.3.4.
