RSI switched from HDF 4.0x to 4.1r2 in the release of 5.2. We ran into a
few problems with the HDF formats written by other programs and read by
IDL. In our case, once everyone was using the same HDF libraries
everything worked again. When we had different version of the libraries,
neither IDL nor non-IDL programs could read the files correctly.
