Testing
-------
+ - Disabled running of MPI Atomicity tests for OpenMPI major versions < 5
+
+ Support for MPI atomicity operations is not implemented for major
+ versions of OpenMPI less than version 5. This would cause the MPI
+ atomicity tests for parallel HDF5 to sporadically fail when run
+ with OpenMPI. Testphdf5 now checks if OpenMPI is being used and will
+ skip running the atomicity tests if the major version of OpenMPI is
+ < 5.

- Fixed a testing failure in testphdf5 on Cray machines
On some Cray machines, what appears to be a bug in Cray MPICH was causing
