[Bug c++/21971] New: class friend declaration doesn't allow use in class scope

["jconner at apple dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following code:

  class a {
    friend class b;
    b *pb;
  };

Produces an error message in the current mainline (4.1.0 development):

  bar.c:3: error: ISO C++ forbids declaration of 'b' with no type
  bar.c:3: error: expected ';' before '*' token

14882:2003, 11.4.7, indicates that this should be allowed:

  "A name nominated by a friend declaration shall be accessible in the scope of the class containing the 
friend declaration."

This is a regression from 4.0.
