Yes, in strict ansi mode Compaq C++ doesn't implement DR45 resolution. (See
also the thread "[test] missing friend declaration in class fixed_mapping?")

There were quite a number of failures due to this and I was hoping I found
all of them, but it seems you were faster than me on this one.

As Dave has already said, adding a friend declaration is usually the best
way to solve this, but I can't say if there are other compilers that will
choke on the friend declaration.
