Awesome, thanks much James.

Is there a pre-existing flag or naming convention for architecture-related build flags? Obviously we want to align with existing precedent, and get the HotSpot and JDK sides to use the same flag. :-)

Is there someone who can help restore the 32/64-bit build-ability for the JDK side, or at least direct us as to where we can start filing a CR?
