Import libs like static libraries adhere to the same specs of PE-COFF 
versus OMF.

So if you want things to work without much hassle, hello -m64!

Thanks, adding `--arch=x86_mscoff` to the dub call and then also 
adding `"libs": ["wldap32"]` fixed it. Is there a way to force 
dub to use that architecture? I could add it as dflags argument 
but then it outputs a warning that I should use --arch instead. I 
don't want users of my library to have that linker error

Looks like you either have to make a .defs file manually or create/find 
a OMF based import lib.

I did find this[0] no idea if it'll work with Optlink without changes.

FYI .defs file is nice since Optlink will recognize it but MSVC link 
won't. Example[1] note that dxva2 has a .def file in same directory but 
it will work for all Windows builds since MSVC provides its own import lib.
