Oh, excuse my misunderstanding. I took this previous statement of yours:

[Michael Stevens] The error seems to indicate a namespace problem rather then
something specific to member template friends?
[Stefan Slapeta] Yes. Both 7.1 and 8 show exactly the same behaviour [...]

as meaning that you endorsed the pov that the problem was not template-related.
(Later on on the paragraph, your position is made clearer, though.)

Anyway, thank you for the further explanation and for trying
the tests. I'll update my lib accordingly to this info.

I guess we'd need more direct exposure to the compiler to determine
this. Peter seems to point out that MSVC 8.0 has made some actual
progress in supporting member *class* template friends, but I don't really
know.
