            Bug ID: 84894
           Summary: [F2018] provide iso_fortran_binding.h
           Product: gcc
           Version: 8.0.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: damian at sourceryinstitute dot org
  Target Milestone: ---

Fortran 2018 requires that compilers provide an iso_fortran_binding.h C header
file for further interoperability with C.   Such a file was on the fortran-dev
branch in 2013:

https://gcc.gnu.org/viewcvs/gcc/branches/fortran-dev/libgfortran/ISO_Fortran_binding.h.tmpl?&view=markup#l1

This bug is being submitted to track progress and interest in this feature and
to preserve a link to the above file as a potential starting point.  The lack
of iso_fortran_bindin.h currently blocks MPICH 3.2 from providing gfortran
users the mpi_f08 module that the MPI 3.1 standard requires.
