This is a bug in the MPI-2 specification, which the mpi.h header file 
(specifically, the mpicxx.h file included by mpi.h) is warning you 
about.  To work around this, try including mpi.h before stdio.h (and 
xxxstream.h).  Alternately, if you aren't using SEEK_SET etc, #undef them 
before including mpi.h .
