Ok, thanks for your help! I think I'll change then my code to avoid the name hiding
thing, hopefully you'll see multi_index tests go green for vacpp-8.0 in the next

As for whether the original test (with name hiding) is legal or not, well, I don't
really know, but I'd love to have the opinion of some C++ guru.
