[Bug c++/30248] New: regression: friend no longer declares classes

[tony at perforce dot com]

The following code compiles under gcc-3.3 and earlier versions, but not under
versions of gcc 4 up to and including gcc-4.0.3 (and possibly later).

class Foo
{
    public:
        // This should act as a forward declaration of class Bar
        friend class Bar;
        Foo( Bar *b ) { bar = b; }

    protected:
        Bar *   bar;
};

class Bar
{
    public:
        Bar( Foo *f ) { foo = f; }

    protected:
        Foo *   foo;
};
