Thanks for pointing this out. This trips me up every time I use  
MPICH2, because after fixing the problem I forget again :)

How about putting a

        #define MPICH_IGNORE_CXX_SEEK 1

at the top of boost/mpi/config.hpp, before the inclusion of mpi.h?

If that works for you, I'll go ahead and make the change in  
Subversion. I'd normally just test this myself, but I don't have easy  
access to an MPICH2 installation at the moment.
