This commit: * Adds the configury to figure out how many Fortran INTEGERs are necessary to represent the C MPI_Status (which now includes a size_t member). * Sets MPI_STATUS_SIZE to this value in mpif-config.h.in. * Adds a big comment in status_c2f.c explaining why the no changes were necessary to how we copy statuses between Fortran and C. This commit was SVN r23472.
