 * Purpose:     This program is run to generate a HDF5 data file with fill
 *              value property.  A new fill value design has been put into
 *              library v1.5.  To test compatibility between v1.4 and v1.5,
 *              compile and run this program, it will generate a file called
 *              fill_new.h5.  You need to move it to the /test directory 
 *              in HDF5 v1.4 source codes.  The fillval.c program will read it.
 *
