Hi, Michael,
  I checked and found MPI_FINALIZE did have an explicit interface, at least in MPICH-3.1.3. You can search the file mpi_base.f90 in your MPICH build.
  We recently fixed the explicit interface problem in  MPI Fortran 2008 bindings.  You need to "use mpi_f08" in your code.  A paper on that is at http://dl.acm.org/citation.cfm?id=2642777
  The new bindings are already included in MPICH-3.2a1. It requires Fortran2008 + TS29113 capable compilers, such as Cray ftn 8.3.3+ or gfortran-dev. If you'd like to have a try, I can instruct you how to do that.

  Thanks.

Dear developers of MPICH,

For your convenience, I forward the emails in mvapich-discuss  concerning the missing Fortran bindings.
Possibly this I can encourage you  a bit, adding (as OPENMPI did it successfully)  the missing explicit Ftn-interfaces in the mpi-module
for those MPI-routines with parameters of "Choice"-type?

At least:  You may add the explicit Ftn-interface for the sbr  MPI_FINALIZE . It is missing in MPICH-3.0.4 too.

Sorry, I wanted to send my email not to Jonathan alone, but to the mvapich-discuss.

Thank You, Jonathan, for this hint.
Indeed, the problem with the missing explicit Ftn-interfaces in the mpi-module are  the arguments of "choice"-type.  Fortran 95 don't like them.
So the MPI-3.0  Standard document contains a complicated chapter 17.1  with these things.
As a consequence, MPICH seems to have chosen the slim way omitting in the mpi-module ("use mpi") the explicit Ftn-interfaces for MPI-routines with choice-type arguments, whereas OPENMPI has chosen the cumbercome way providing  the explicit Ftn-interfaces even for these MPI-routines. They succeeded.
For details: In November there were some emails discussing this issue in the OPENMPI-forum.

Greetings
Michael Rachner

Hello Michael.  My investigation turned up the same issue in MPICH-3.1.3.  MVAPICH2-2.1a is based on MPICH-3.1.2 so it inherits the same behavior.

Here is a snippet from MPICH's user guide:

    4.2 Special Issues for Fortran

    MPICH provides two kinds of support for Fortran programs. For
    Fortran 77 programmers, the file mpif.h provides the definitions of
    the MPI constants such as MPI COMM WORLD. Fortran 90 programmers
    should use the MPI module instead; this provides all of the
    definitions as well as interface definitions for many of the MPI
    functions. However, this MPI module does not provide full Fortran 90
    support; in particular, interfaces for the routines, such as MPI
    Send, that take “choice” arguments are not provided.

It sounds like these are routines with ``choice'' arguments.
