Guide for dmd development @ Win64?

[Dicebot via Digitalmars-d]

I have an awkward problem - recently installed an extra Win8 
(x64) OS to test some of weird failures I can't reproduce on 
Linux and after half a day still can't configure basic 
development setup for dmd/druntime/phobos >_<

This was quite helpful 
http://wiki.dlang.org/Installing_DMD_on_64-bit_Windows_7_(COFF-compatible) 
but unfortunately it only covers configuring pre-build dmd 
distribution package and I can't find anything similar for 
developers.

Can you Windows guys please share how do you get things done? :) 
I am currently stuck with `make -f win64.mak` in druntime 
complaining about incompatible dll's.
