I don't know. Somewhere in between.

Remember that EDG reported that it took them 3 man-years just to 
implement one C++ feature - exported templates - and the EDG guys know 
what they're doing around compilers.

But there's little reason to implement a D compiler from scratch. For 
open source uses, you can just go ahead and use dmd. For closed, 
proprietary uses, we can work something out.
