[mpich-discuss] missing mpi_f08 module in MPICH 3.2

[Kenneth Raffenetti]

F08 bindings will build if they pass the included compiler tests during 
configure. Unfortunately gfortran is unable to build the binding. The 
latest Intel compiler suite will work, if you have access to that.

Could someone please point me to documentation on using the bindings?  My installation of MPICH 3.2 doesn’t find the mpi_f08 module described in MPI 3.1 standard.  My draft copy of the standard states the following at the beginning of Section 17.1.2: "An MPI implementation providing a Fortran interface must provide a module named mpi_f08 that can be used in a Fortran program.”  Below is an example of what I’m seeing.
