When running serialization tests with mingw-64/gcc on Windows I get 
repeated errors of the form:

..\..\../boost/archive/detail/basic_oarchive.hpp:64:5: error: function 
'boost::archive::detail::helper_collection& 
boost::archive::detail::basic_oarchive::get_helper_collection()' 
definition is marked dllimport
      get_helper_collection(){

Is this a known problem ?

Testing with VC++ does not give any errors.
