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.).
