digitalmars.D - Link errors when compiling shared lib on windows

- kinke (5/11) Nov 01 2017 Try less, especially no `-defaultlib` overridden with a Linux

That's the only way I've been able to create a working DLL. I've never had to add the -defaultlib option with LDC on Windows. Here's a post describing all the steps I took to make a DLL that can be called from R: https://lancebachmeier.com/computing/d-from-r-windows.html The references to R are not important. Should be straightforward to adopt for your use case.
