I hate to say this but hppa1.1-*-rtems* includes config/pa/rtems.h after
config/pa/pa-pro-end.h so ends up overriding the CPP_PREDEFINES
settings.
So -D__PRO__ has to be added to config/pa/rtems.h as well.
It isn't obvious because the include order is from config.gcc but this
is basically how all of the *-rtems* targets are constructed. We
baseline
another similar target and slightly modify it for RTEMS. :)
