 *
 * This test case performs the following actions:
 *
 * - Run the event constant and number test for all 32 event constants.
 *
 * - Check that RTEMS_PENDING_EVENTS is a constant expression which evaluates
 *   to a value of zero.
 *
 * - Calculate the value of a bitwise or of all 32 event constants.
 *
 *   - Check that the value is equal to RTEMS_ALL_EVENTS.
 *
 * - Validate the Event Manager directive options.
 *
 *   - Check that RTEMS_EVENT_ALL is equal to zero.
 *
 *   - Check that RTEMS_EVENT_ANY is a power of two.
