I disagree. And so do most modern compilers.
Would you care to point me to the text justifies what you said?
Thanks
Martin

Synopsis: g++ 3.2 error parsing a scoped friend declaration
State-Changed-From-To: open->closed
State-Changed-By: bangerth
State-Changed-When: Fri Dec 13 12:52:01 2002
State-Changed-Why:
Your code is ill-formed: you can't specify just one instance
of a template as a friend, you have to specify all of them.
The syntax for this would be
template <typename Y> friend class ::A;
which is accepted by all compilers since 2.95.

This is still failing in 3.2. The problem was first reported against 2.95.2. It was analyzed by Martin v. Loewis as a known parser limitation but, AFAIK, we never entered in GNATS.
