I think it is supposed to work. The standard says that the value
must be Swappable, MoveConstructible, and MoveAssignable. I think
that std::unique_ptr meets those requirements.
I think this is a bug in libstdc++-v3. Looking at the code, I think
this means that __introsort_loop can't assume that it can pass values
to std::__median.
It is a "bug" in that not all of libstdc++-v3 has been updated to
C++0x. Sort is one such example.

Would it be useful to file a bugreport (at least for keeping track of
this) or can this fact be assumed to be commonly known by the
responsible persons, meaning that it is on their todo-list anyway? Maybe
i can take a closer look at this during the xmas holiday and create a
patch to fix this issue. Would this need any paperworks with the FSF?
