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.
