0066  * @brief Tests the Event Manager API.
0067  *
0068  * This test case performs the following actions:
0069  *
0070  * - Run the event constant and number test for all 32 event constants.
0071  *
0072  * - Check that RTEMS_PENDING_EVENTS is a constant expression which evaluates
0073  *   to a value of zero.
0074  *
0075  * - Calculate the value of a bitwise or of all 32 event constants.
0076  *
0077  *   - Check that the value is equal to RTEMS_ALL_EVENTS.
0078  *
0079  * - Validate the Event Manager directive options.
0080  *
0081  *   - Check that RTEMS_EVENT_ALL is equal to zero.
0082  *
0083  *   - Check that RTEMS_EVENT_ANY is a power of two.
