* Purpose: Create a two datasets with compound datatypes, one with no array
* fields and one with array fields.
* This program is used to create the test file `tarrold.h5' which has a
* datatypes stored in the older (version 1) style in the object headers.
* To build the test file, this program MUST be compiled and linked with
* the hdf5-1.2.x series of libraries and the generated test file must be
* put into the 'test' directory in the 1.3+ branch of the library.
* The test file should be generated on a little-endian machine with
* 16-bit shorts, 32-bit floats, 32-bit ints and 64-bit doubles.
