Thanks for that information. I think what I'll want to do, for a
first cut, is always produce 64-bit literals for 64-bit capable

I'm going to wait until after the review period to start on fixing
the 64-bit support. Since I don't have a local 64-bit compiler
I'll be working blind and my first few efforts will be dead wrong.

At an initial glance it looks like 64-bit support should be
achievable without heroic efforts. But it certainly won't come
along for free.

Thanks again Reece.
