There was a problem hiding this comment.
One minor comment regarding the indentation. Once fixed this can be merged.

MPI-4 will introduce the concept of the 'initial error handler'. This is the error handler that is set before MPI is initialized and after MPI is finalized, and can be selected from mpiexec/SPAWN info key parameters.
This also adds MPI_ERROR_CLASS, and MPI_ERROR_STRING to the functions that can be called before/after MPI_INIT and are always thread safe.
