now going to proceed with the instructions for Building DRuntime 
(with Visual Studio):

https://wiki.dlang.org/Building_under_Windows

open a command prompt:

> call "C:\Program Files (x86)\Microsoft Visual 
> Studio\2017\Enterprise\VC\Auxiliary\Build\vcvarsall.bat" x64

(ok it seems to run fine)

(instructions then say to run this:
set VCDIR="C:\Program Files (x86)\Microsoft Visual 
Studio\2017\Enterprise\VC"

but that env variable is already set in the win64.mak  ?? so why 
type the above command in?? which has a different value to what 
is in my win64.mak anyway ??

my settings in that file are (I have VS2017 enterprise installed):

----
.....

VCDIR=C:\Program Files (x86)\Microsoft Visual 
Studio\2017\Enterprise\VC\Tools\MSVC\14.15.26726

SDKDIR=C:\Program Files (x86)\Windows Kits\10\Include\10.0.17134.0

.....

CFLAGS=/Z7 /I"$(VCDIR)"\INCLUDE /I"$(SDKDIR)"\Include

....
-----

so I'll skip that part of the instruction and look at the next 
one:

make -f win64.mak -j4 "VCDIR=%VCDIR%" target

well, since I'm not setting VCDIR manually, but using the one in 
the win64.mak, I'll change that instruction to something simpler: 
make -f win64.mak

c:\source\D\druntime>make -f win64.mak
"make" -f mak/WINDOWS import 
DMD="..\dmd\generated\windows\release\64\dmd" HOST_DMD="dmd"
