32 bit is the default for now. I don't know what Walter intends to do in the 
long run. If it were like gcc, then the default platform would be the platform 
which the compiler is built for (which is exactly what it's doing right now), 
but as far as I know, Walter has no plans to port dmd to x86_64.

So, for now 32 bit is the default. It may or may not change later to be the 
platform that you're building on. Ideally though, it would be like gcc and we'd 
actually get a 64 bit version of dmd at some point.
