[svn-r5171]

Purpose:
    New feature
Description:
    Fill-value's behaviors for contiguous dataset have been redefined.
    Basicly, dataset won't allocate space until it's necessary.  Full details
    are available at http://hdf.ncsa.uiuc.edu/RFC/Fill_Value, at this moment.
    These two file test backward compatibility with 1.4.
Platforms tested:
    Linux 2.2.

+ * 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.
