#  NDEBUG (C library)
#     if defined asserts do not generate code.  This is commonly used
#     as a command line option.

#  RTEMS_TEST_NO_PAUSE (RTEMS tests)
#     do not pause between screens of output in the rtems tests
#
#  STACK_CHECKER_ON (RTEMS support code)
#     If defined, stack bounds checking is enabled.
#
#  STACK_CHECKER_REPORT_USAGE (RTEMS support code)
#     If this and STACK_CHECKER_ON are defined, then a report on stack usage
#     per task is printed when the program exits.
#
#  RTEMS_DEBUG (RTEMS)
#     If defined, debug checks in RTEMS and support library code are enabled.
