Purpose:
bug fix
Description:
Due to the version bump? of HDF4 from 4.1 to 4.2, the original oversimplified algo. test hdp has to be updated to be consistent with the version bump; otherwise, some tests will be skipped.
    [describe the bug, or describe the new feature, etc]
Solution:
Add another line for the current algo. to make sure hdp will be used for 4.2 series as well.
    [details about the changes, algorithm, etc...]
    [Please as detail as you can since your own explanation is
    better than others guessing it from the code.]
Platforms tested:
Linux 2.4( will test other platforms after source code changes. the change is too minimum to be tested on other platforms.)
    [machines you have tested the changed version.  This is absolute
    important.  Test it out on at least two or three different platforms
    such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and
    64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]
