I would advise against using optlink, make sure your object file 
format is COFF. I can recommend setting up your project for 
dub[1]. All I had to do is add this to dub.json:

  	"libs": [
		"Gdi32",
		"Comdlg32",
		"Winspool",
		"Ws2_32",
		"wntab32x",
		"User32"
		],

and compile with `dub build -a=x86_mscoff` for 32bit or `dub 
build -a=x86_64` for 64bit. It just works. Granted I also have 
this in dub.json

   	"lflags-x86_mscoff": ["/NODEFAULTLIB:LIBC.lib"]

but I believe that is necessary because of some other libs that 
we link with.
