Announcing an all-new, exciting errata item!


In MPI-3.1, the Fortran INTEGER-array-style status object constant MPI_STATUS_SIZE, MPI_SOURCE, MPI_TAG, and MPI_ERROR are explicitly only defined in Fortran.  This does not make sense, because Fortran INTEGER-array-style status objects are also accessible in C.

This errata therefore creates C versions of these constants: MPI_F_STATUS_SIZE, MPI_F_SOURCE, MPI_F_TAG, and MPI_F_ERROR.  Mercifully, it's a pretty short text change.

The v3.x PR and PDF and v4.0 PR and PDF are linked from the above issue.
