Right, there's certainly that. But that has nothing to do with whether 
you're trying to build a 64-bit or 32-bit program, and (at least for 
Windows) it isn't even an issue at all unless you actually are hitting 
that limit (unlikely for a newcomer to D). It sounded like steven 
kladitis was worried about just being able to create 64-bit programs. 
For that, it makes no difference if the compiler itself is a 32- or 
64-bit build.
