[MPIWG Fortran] What is BIND(C)?

[Craig Rasmussen]

I don't think Intel does yet (but actually I will check).  Intel supports the IGNORE_TKR and so Jeff is using the Intel compiler with compiler directives to support MPI-3.

Surprisingly, the latest gfortran supports type(*) and dimension(..) partially, as in it will act like IGNORE_TKR (I think) but actually doesn't pass the new C descriptors yet.

You'll need to build with a non-gfortran compiler to get the mpi_f08 module built (e.g., the Intel fortran compiler).
