Older gfortran compilers (e.g., the gfortran that ships in RHEL5) do not support ISO_C_BINDING, and therefore do not support the TYPE(C_PTR) type. As such, they cannot support the overloaded interfaces for MPI_WIN_ALLOCATE_SHARED and MPI_SHARED_QUERY that are mandated in MPI-3. So we separate those interfaces out into a separate .F90 file that is #include'd in the tkr mpi.F90 file. In this separate .F90 file, we use an #if to determine whether the compiler supports ISO_C_BINDING or not. Also re-jiggered the order of testing in ompi_setup_mpi_fortran.m4: we now need to test whether the compiler supports ISO_C_BINDING even when we're only building the mpi module (not strictly when we're building the mpi_f08 module). Finally, tweaked the use-mpi-tkr/Makefile.am to: * Add some proper dependencies for mpi.F90 * Allow the general AM compilation to be used instead of supplying a specific rule for compiling mpi.F90 cmr=v1.8.2:ticket=trac:4736 This commit was SVN r32204.
