(JTH - 2018/07/16, HDFFV-10467)
+ - Added checks of the defined MPI_VERSION to guard against usage of
+ MPI-3 functions in the Parallel Compression and "big Parallel I/O"
+ features when HDF5 is built with MPI-2. Previously, the configure
+ step would pass but the build itself would fail when it could not
+ locate the MPI-3 functions used.
+
+ As a result of these new checks, HDF5 can again be built with MPI-2,
+ but the Parallel Compression feature will be disabled as it relies
+ on the MPI-3 functions used.
