Sorry if this turns out to be a dup, but I think my original message
got bounced by the list bouncer.

IAydin's suggestion to add that flag to the global <cxxflags> fixes
the problems, but that's not
necessarily the solution to hang your hat on - it should work out of
the box (albeit the user may have to add the path to his mpicxx
wrapper anyway).

I tried your suggestion, but it didn't work.  I tracked down the
problem to three files that are including mpi.h directly, but not
including boost/mpi/config.hpp:

./boost/mpi/detail/packed_oprimitive.hpp
./boost/mpi/detail/packed_iprimitive.hpp
./boost/mpi/detail/mpi_datatype_primitive.hpp

I've submitted two patches tha define MPICH_IGNORE_CXX_SEEK in those
three files and in boost/mpi/config.hpp.
