[MPIWG Fortran] What compilers support TS 29113?

[Jeff Hammond]

The "except for"="does not work" standard is a fantastic way to
demoralize every programmer this side of Don Knuth.  Has MPICH ever
worked?

>> Gfortran 5.1 fails the MPICH test because ISO_Fortran_binding.h isn’t available for GCC 5.1 (I don’t know if that’s the right test, but that’s what it does).
