[Bug libstdc++/43595] std::unique incorrectly assumes transitive property on functor, operator==

[chris at bubblescope dot net]

Fixing this would make std::unique quite a bit less efficient. I personally
believe the intention was always to make it an equivalence relation and as you
say C++0x tightens up the condition.

If this had come up 5 or 6 years ago, I might have suggested fixing it, but
changing it now would produce an incompatibility between our C++03 and C++0x
implementations unnecessarily.

Does any other compiler get this right? If they did that would make a more
convincing case, but I'm fairly sure they don't.
