Without the patch, we get an ICE for code like

namespace N {

    template<class T> class C
    {
        template<class U> friend class C;
    };

}

This was reported twice in July, in

http://egcs.cygnus.com/ml/gcc-bugs/1999-07/msg00569.html and
http://egcs.cygnus.com/ml/gcc-bugs/1999-07/msg00126.html

There is no work-around, other than removing the namespace, or the
friend declaration.
