Windows devs - how are you building dmd, druntime, phobos?

Yup, welcome to hell. Everything is basically hidden behind 
configuration files somewhere in autotester. It took a long time 
to figure out how to compile DMD with VS. If you don't want to do 
it, good luck trying to figure out how to do it without VS.

To build phobos/druntime you actually need to remove a "/" from 
the environment variable, why was this done? Because fuck you 
that's why, no one on the D team is competent enough with Windows 
to make it work with the default expected value.

     cd $ROOT/src/druntime
     make -f win64.mak clean
     make -f win64.mak VCDIR="${VCINSTALLDIR::-1}" 
DMD=../dmd/src/dmd druntime32mscoff

     cd $ROOT/src/phobos
     make -f win64.mak clean
     make -f win64.mak VCDIR="${VCINSTALLDIR::-1}" 
DMD=../dmd/src/dmd phobos32mscoff


I also use git bash to run a .sh script since testing DMD 
requires shell scripts. Need to do a workaround with 
vcvarsall.bat so that it loads all the appropriate environment 
variables.

$ROOT is just the root directory that's set in the editor I use.

DMD requires all the repositories be in the same folder. So dmd, 
druntime, and phobos need to be in one folder.

Good luck!

Oh one more thing. DMD/Phobos/DRuntime use Digital Mars' MAKE to 
build with. While the testing suite uses GNU MAKE. Guess what D 
puts in your root path called "make", yup their digital mars' 
MAKE instead of what people would expect to be GNU Make (and 
those that do already have a GNU Make in their path). Why? 
Because fuck you.
