It would be fairly trivial. It could be added to CPP_PREDEFINES in
pa-pro-end.h

Very very few. The embedded PA consortium basically broke up in the late
90s and we haven't had customers for these tools since. As a result they
are basically unsupported/bitrotting. Looking to the future, I don't expect
to see embedded PA customers. It just doesn't make sense given the
availability to MIPS, PPC & Arm embedded processors.

Vlad can you move the -D__PRO__ into the CPP_PREDEFINES in pa-pro-end.h?
