>Description:
G++ seems to have problems with names in
template classes. It refuses to have a
name and a friend with the same name in
one class definition.
It complains about a non-existant forward
declaration.
>How-To-Repeat:
Source:

template < typename N > struct A;
template < typename N > A<N> operator+ (A<N> const &, A<N> const &);

template < typename N > struct A
{
        A<N> const & operator+() const;
        friend A<N> operator+<N> (A<N> const &, A<N> const &);
};

A<bool> b;

Command Line:
c++ -v --save-temps -c dumb3.cpp -o dumb3.o

Output:

Comment:
The code is compiled, if you leave one of the two
lines inside the struct definition away.
