Synopsis: lookup of anonymous structure members does not work as in C frontend

State-Changed-From-To: open->closed

State-Changed-Why:
    This isn't legal.
      struct Bar { struct Foo; };
    This is a forward declaration of Bar::Foo, and so doesn't do
    what you think it does.  Note that this is a Microsoft VC++
    extension that we don't support in the C++ front end.
