Hi,

I have reached to build Boost.Conversion and Boost.Fusion with clang-2.9 
(03 and 0x) without any major trouble after updating the trunk. However 
I get a warning that could eassily be removed

In file included from 
../../../boost/fusion/algorithm/iteration/reverse_fold.hpp:14:
../../../boost/fusion/algorithm/iteration/detail/fold.hpp:189:48: 
warning: unused parameter 'it0' [-Wunused-parameter]
             call(State const& state,It0 const& it0,F f)
