[svn-r3973] Purpose:
Bug fix Description: The t_mpi used to fail and exit if any error detected. That aborted other process in a "make check" situation. Solution: Introduced a new error verification as INFO. INFO is for information only. It does not increase nerrors count. The program always exits with 0. Platforms tested: eirene with mpich.
