[mpich-discuss] missing mpi_f08 module in MPICH 3.2

[Jeff Hammond]

This is the MPICH configure error:

configure:44317: gcc-8 -c    -O2
-I/home/jrhammon/Work/MPI/MPICH/git/build/src/mpl/include
-I/home/jrhammon/Work/MPI/MPICH/git/src/mpl/include
-I/home/jrhammon/Work/MPI/MPICH/git/src/openpa/src
-I/home/jrhammon/Work/MPI/MPICH/git/build/src/openpa/src -D_REENTRANT
-I/home/jrhammon/Work/MPI/MPICH/git/build/src/mpi/romio/include conftest.c
>&5
conftest.c:155:10: fatal error: ISO_Fortran_binding.h: No such file or
directory
 #include <ISO_Fortran_binding.h>
          ^~~~~~~~~~~~~~~~~~~~~~~

It has a trivial reproducer:

$ cat mcve.c
#include <ISO_Fortran_binding.h>

int main()
{
    return 0;
}

$ gcc-8 -c mcve.c
mcve.c:1:10: fatal error: ISO_Fortran_binding.h: No such file or directory
 #include <ISO_Fortran_binding.h>
          ^~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

Relevant GCC content:

https://gcc.gnu.org/bugzilla/show_bug.cgi?format=multiple&id=48820
https://gcc.gnu.org/ml/fortran/2012-07/msg00115.html

I don't understand why GCC hasn't implemented this header in the 5+ years
that they've known that MPI needs it.
