Confirmed, but this is already fixed on mainline due to Kriang's
untiring efforts to stomp friendship bugs.

True, but this is a showstopper for me as I have been unable to find any
viable workaround.  As 3.4 will not be released before Spring 2004,
this is not a nice situation.  Of course, if I am the only one
on Earth to have this problem I guess I will have to live with it.

Closing as most likely there will not be another 3.3.x based compiler and this is not a regression.

What's wrong with
    template <typename S> friend void N::foo(S);
?

It is a temporary workaround I can live with.
Thanks!
