System configuration in RTEMS is performed by <rtems/confdefs.h> which uses 
various application defined pre-processor defines.  The actual configuration 
structures are defined if CONFIGURE_INIT is defined before the include of 
<rtems/confdefs.h>.  You must define CONFIGURE_INIT and inlude 
<rtems/confdefs.h> at most once.
