Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.

|
*
|
|
* Purpose: Create a dataset with a null dataspace and an attribute
|
|
* with a null dataspace.
|
|
* This program is used to create the test file `tnullspace.h5' which
|
|
* has dataspaces stored in the newer (version 2) style in the object headers.
|
|
* To build the test file, this program MUST be compiled and linked with
|
|
* the hdf5-1.7+ series of libraries and the generated test file must be
|
|
* put into the 'test' directory in the 1.6.x branch of the library.
