* MPI-3.1 section 3.6, page 45, states that the mpif.h and mpi module
* interfaces for MPI_BUFFER_DETACH ignore the buffer argument.
* Therefore, for the mpif.h and mpi module interfaces, we use a dummy
* variable and leave the value handed in alone.
*
* The mpi_f08 implementation for MPI_BUFFER_DETACH therefore is a
* separate routine in the use-mpi-f08 directory (it's not built in
* the mpif-h directory because of all the different combinations of
* supporting weak symbols (or not), building the profiling layer (or
* not), etc.).
*
* Note that we only need to build this function once -- the F08
* interfaces for MPI_BUFFER_ATTACH and PMPI_BUFFER_ATTACH both
* bind(C) to the name ompi_buffer_detach_f08.
