Well that certainly explains things.  That makes my comment on the boost mailing list a bit moot, as well.  Thanks for the pointer!

It's been three years since that thread was posted.  Do the arguments still apply?  I assume they do.

I agree.  I merely mentioned it because of the "largest native integer" comment above.

Thanks again!
