#     If your version of gcc supports the -mcpu32 option use the top
#     version, otherwise use the bottom set of flags to accomplish the
#     same thing.
#
#     NOTE:  Before binutils 2.6, the -mcpu32 flag was not available
#            if your gas does understand this, then use the alternative.

#     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.
