Thanks Sherm. It looks like there might be some benefit for high-end users
who are likely to go beyond 4GB VM but we can postpone it 'til then.

Does your app need more than 4G of virtual memory space?
Does your app spend a significant amount of its time splitting huge
numbers into 32-bit "chunks" so it can cope with them?
If you answered "no" to these questions, don't bother recompiling. It
won't help.
