[MPIWG Fortran] What compilers support TS 29113?

I used gfortran 4.9.1 and I have build an include file which adopted the definitions of the missing
ISO_Fortran_binding.h to the implementation of gfortran (include file libgfortran.h) .
Using this I could implement the Fortran binding for TS29113. It works except for arrays of derived Fortran Types
which are always transferred via copy in/copy out.

gfortran no, not even with 5.1.0 . It does have a lot of F 2008, but not even all of it, according to https://gcc.gnu.org/wiki/Fortran2008Status and https://gcc.gnu.org/wiki/TS29113Status .
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). See also https://gcc.gnu.org/onlinedocs/gfortran/Further-Interoperability-of-Fortran-with-C.html#Further-Interoperability-of-Fortran-with-C .
