The constant MPI_ROOT is not universally defined in all current
shipping MPI implementations.

Is there any MPI function/call that requires MPI_ROOT?

 From the complete reference it appears that MPI_ALLGATHER might be
the one routine.

This all relates to portability, code I write using OpenMPI has to
work on other systems not using OpenMPI.
