Apart from the fact that this is an unreleased compiler, whether or not that 
test passes (and it's *very* strict, hence the "tricky" name), depends on 
the implementation of std::reference_wrapper.  I suspect - but haven't had 
time to check - that this is a difference between the TR1 specification and 
C++11, in that if memory serves, TR1 requires inheritance from 
std::unary_function, where as C++11 does not.  Given that the test case 
tests strict adherence to TR1, such failures should probably just be marked 
up as expected.   Oh wait.... this is in C++03 compilation mode?   In that 
case it depends on Boost's reference wrapper, which has never been TR1 
conforming.

PS, can we deprecate Boost.TR1 yet? ;-)
