it will be an incremental port using both C++ and D code
so the DMD C++ base needs headers from the D based module replacements

that will just not work for an project of that size - or better - there 
are several tries of from-scratch without success out there

an incremental port and then refactor is the best/fasted and error-free 
thing we can get

benefits:
-will help to find more bugs/missing features/tools in the C/C++ <-> D 
conversion/adaption area (which is still a big plus for D)

-keeps both the pure D and the semi-pure :) D guys (Walter,gdc,ldc 
frontend developers) in the same boat

-the dmd frontend will become the very first community driven BIG 
project that can be a much better orientation for bug-prevention 
designs/future D ideas etc. then every thing else

etc...
