This doesn't compile because ignore_skeleton_oarchive is a template 
class not a specific type. There is a similar macro in 
mpi_datatype_oarchive.hpp with an mpi_datatype_oarchive specialization:
BOOST_SERIALIZATION_REGISTER_ARCHIVE(
  boost::mpi::detail::ignore_skeleton_oarchive
  <boost::mpi::detail::mpi_datatype_oarchive>)

but with all the forward declaration includes, I can't actually work out 
which classes have been fully defined when this indirectly invoked via 
the #include  "communicator.hpp".

I'm guessing the instantiation is not actually built because at the 
point of BOOST_SERIALIZATION_REGISTER_ARCHIVE, 
ignore_skeleton_oarchive<mpi_datatype_oarchive> is somehow incomplete???
