 Hi all,
 Visual C++ 2013 has only partial support for defaulted functions:
 h t t p : / / m s d n . m i c r o s o f t . c o m / e n - u s / l i b r a
 r y / h h 4 0 9 2 9 3 . a s p x

 I received the following error while running bjam with Visual Studio 2013
 (but see further down for successful resolution):

 bjam --with-python python-debugging=off threading=multi variant=release
 link=shared address-model=64 toolset=msvc-12.0 stage

 --- hopefully irrelevant parts removed ---

 .\boost/graph/detail/adjacency_list.hpp(298) : error C2610:
 'boost::detail::stored_edge_property<Vertex,Property>::stored_edge_property(boost::detail::stored_edge_property<Vertex,Property>
 &&)' : is not a special member function which can be defaulted
         .\boost/graph/detail/adjacency_list.hpp(304) : see reference to
 class template instantiation
 'boost::detail::stored_edge_property<Vertex,Property>' being compiled

 ---- error end ----
 I then defined BOOST_NO_CXX_DEFAULTED_FUNCTIONS in
 boost/config/compilers/visualc.hpp and it appears that everything has
 compiled successfully. Perhaps there could be more fine-grained support
 for what VC 2013 supports and doesn't, but for me, it's not relevant, so
 here is my patch:
