+ *
+ * @brief Tests the option constants of the Classic API.
+ *
+ * This test case performs the following actions:
+ *
+ * - Validate the non-default option constants.
+ *
+ *   - Check that RTEMS_EVENT_ANY is a power of two.
+ *
+ *   - Check that RTEMS_NO_WAIT is a power of two.
+ *
+ * - Validate the default option constants.
+ *
+ *   - Check that RTEMS_DEFAULT_OPTIONS is equal to zero.
+ *
+ *   - Check that RTEMS_EVENT_ALL is equal to zero.
+ *
+ *   - Check that RTEMS_WAIT is equal to zero.
+ *
+ * - Calculate the bitwise or of all non-default option constants.
+ *
+ *   - Check that the count of set bits in the calculated value is equal to the
+ *     count of non-default option constants.  Since each non-default option
+ *     constant is a power of two, this proves that each constant has a unique
+ *     value.
