The problem is that the Digital Mars linker is called but the Microsoft 
linker is run, because they share the same name link.exe. For 
dmd/x64/32mscoff or LDC in general the latter is expected to be used. 
Usually dmd and ldc know how to find the appropriate one, but dub might 
just expect it to be found through the PATH environment variable.

So, try to set your PATH so that the MS linker is found first.
