When building the nasa overflow 2.0aa code with openmpi 1.1.1b3 using
the intel compilers on a Opteron cluster running
SLES 9 with the intel 9 compilers, I get the following warnings when
linking :

in mpif-common.h there are some common block definitions :

      common/mpi_fortran_bottom/MPI_BOTTOM
      common/mpi_fortran_in_place/MPI_IN_PLACE
      common/mpi_fortran_argv_null/MPI_ARGV_NULL
      common/mpi_fortran_argvs_null/MPI_ARGVS_NULL
      common/mpi_fortran_errcodes_ignore/MPI_ERRCODES_IGNORE
      common/mpi_fortran_status_ignore/MPI_STATUS_IGNORE
      common/mpi_fortran_statuses_ignore/MPI_STATUSES_IGNORE

These names are apparently conflicting with the names in the static
library.

Hope this gives you enough to go on.

Thanx to the open-mpi team for the improvements that keep coming with
newer releases of the product.
