I followed the instructions to the letter, same folder names, one 
step at a time, from here...

https://wiki.dlang.org/Building_and_hacking_LDC_on_Windows_using_MSVC

I had to ensure the command prompts were always run as 
administrator. It gave odd error messages if I forgot to do that.

I did it on a fresh install of windows 10, with a fresh install 
of VS2017, I literally tried to replicate everything listed in 
the instructions.

IIRC The only thing I had to do extra was passing 
"-DD_COMPILER=c:\path\to\ldmd2.exe." to ninja, it's listed in the 
section "Building LDC" but doesn't really tell you why you might 
need it.

I'm not 100% sure that's all there was to it but if you can't get 
it to work I can always have a run at it again and keep notes of 
exactly how I got it to work.
