Are there known problems with MultiIndex on the current VC++ 10 beta? 
I'm looking in particular at <URL:http://tinyurl.com/39bmudo>.  The area 
around the line VC++ 10 has a problem with (line 276 of 
distributed_property_map.hpp, the error is on the &std::pair line) is:

typedef multi_index::multi_index_container<
           std::pair<key_type, value_type>,
           multi_index::indexed_by<
             multi_index::sequenced<>,
             multi_index::hashed_unique<
               multi_index::member<std::pair<key_type, value_type>,
                                   key_type,
                                   &std::pair<key_type, value_type>::first>
             >
           >
         > ghost_cells_type;

and the main error is (full instantiation stack in the link above):

D:\boost-test\boost\boost/property_map/parallel/distributed_property_map.hpp(276) 
: error C2440: 'specialization' : cannot convert from 
'boost::detail::parallel::global_descriptor<LocalDescriptor> 
std::_Pair_base<_Ty1,_Ty2>::* ' to 
'boost::detail::parallel::global_descriptor<LocalDescriptor> 
std::pair<_Ty1,_Ty2>::* '
         with
         [
             LocalDescriptor=unsigned int,
             _Ty1=boost::detail::parallel::global_descriptor<unsigned int>,
             _Ty2=boost::detail::parallel::global_descriptor<unsigned int>
         ]
         Standard conversion from pointer-to-member of base to 
pointer-to-member of derived is not applied for template arguments

What I don't see is where the pointer-to-member of _Pair_base comes from; 
is that the correct type for the address of a member that's actually from 
a base class?  Or is this a compiler problem?
