Yes, exactly this. The BIND(C) in Annex A.3 had no real meaning. All rules had been in 17.1.5. I hope you can also agree with the rest of the plan. E.g., your wishes (and also Craig's, Tobias' ...) are included. Best regards Rolf ----- Original Message -----

Here the shortcut:

- Only for optical: Removal of the BIND(C) from all mpi_f08 interface definitions. It has no real meaning in current MPI-3.0, because all about BIND(C) is defined in 17.1.5 and not in the 360 individual interface definitions.

Yes, I agree with this. This means fixes in A.3, for example. To the extent that the document is a specification of the API for users, the BIND(C) is irrelevant. The user CALL statement is unaffected by whether the implementation has BIND(C) or not.

BIND(C) is really only relevant for implementers. In just one place (17.1.5 seems popular) there should be the rules for what is required of an implementation if it specifies BIND(C) on a particular routine, mainly the requirements for the external name, based on how the implementation uses the routine.

Cheers, Bill
