Paul,

I think you're not getting a response because you're asking a lot.  
Without testing by running an executable, this can't be determined 
behaviorally, so your best bet is some sort of lookup.  I would suggest 
you write your own macro, where you set the flag based on known system 
information, and barring that try some link-time flags and use one that 
doesn't generate any errors.

HTH,
