I'm not Kriang but I'm going to answer.  Yes, GCC's behaviour is
wrong.  Compilers that reject the code are right.  See the explanation
I gave in the link pointed to in the original report.  If you want
chapter and verse, see somewhere in 7.3.1.x for namespace members that
talk about friend declarations.
