70 * MPI-3.1 section 3.6, page 45, states that the mpif.h and mpi module
71 * interfaces for MPI_BUFFER_DETACH ignore the buffer argument.
72 * Therefore, for the mpif.h and mpi module interfaces, we use a dummy
73 * variable and leave the value handed in alone.
74 *
75 * The mpi_f08 implementation for MPI_BUFFER_DETACH therefore is a
76 * separate routine in the use-mpi-f08 directory (it's not built in
77 * the mpif-h directory because of all the different combinations of
78 * supporting weak symbols (or not), building the profiling layer (or
79 * not), etc.).
