* environment variable is set to a value that supports virtual
* datasets & external links. Currently that is limited to a
* VOL connector stack that is composed of _only_ the trivial
* single connector stack of the native VOL connector.
*
* It is intended for use in shell scripts.

* Function: main
*
* Purpose: Uses the default file access property lists, which is
* initialized with the VOL connector from the HDF5_VOL_CONNECTOR
* environment variable to determine if virtual datasets & external
* links are supported.
*
* Return: VOL connector supports virtual datasets & external links: EXIT_SUCCESS
*
* VOL connector does not support virtual datasets & external links,
* or failure: EXIT_FAILURE
