*
* @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.
*
* - Check the value of RTEMS_DEFAULT_OPTIONS.
*
* - Check RTEMS_DEFAULT_OPTIONS equals RTEMS_WAIT.
