[Mpi-forum] Compile problems with examples in MPI Standard

[Rolf Rabenseifner]

I'm no specialist on this, but I want that you look at:

 - MPI-2.2 MPI_INIT       (..., char ***argv
           MPI_INIT_THREAD(..., char *((*argv)[])
 - Bill's preference            char (*(*(argv_p[])))
 - current MPI-3.0 (r1486)   
   MPI_INIT and MPI_INI_THREAD  char *((*argv)[])

I would say, if there is no guaranteed backward compatible
change, I would prefere to stay with MPI-2.2 declarations
as they are.

This is only a formal answer after detecting that
Bill's position is not identical to one of
the existing solutions.
