Shared libraries (DLLs) don't work on windows. They only work for
the simplest of all cases (e.g. global functions) and even then
there are pitfalls. Just don't do it. The only viable option
currently is to link statically or put _all_ your D code into one
single Dll and use that Dll from C. Any other use case is bound
to fail. I'm currently working on propper dll support for D but
it is a lot of work.
