[boost] [MPI] Dynamic linking on Windows - mpi_datatype_cache() unresolved means BOOST_IS_MPI_DATATYPE unusable?

Dear all,

It looks like boost::mpi::detail::mpi_data_type_cache() (in
boost/mpi/detail/mpi_datatype_cache.hpp) is missing a declspec
declaration, causing unresolved external symbols when trying to give a
specialization of is_mpi_datatype.

Is my use case (Windows, dynamic, "simple" types that qualify for
is_mpi_datatype) unusual so that this hasn't been picked up before? Or
am I missing something obvious?

Thanks in advance for any help
Pete
