Building unbound on Windows?

[Jeff Westhead via Unbound-users]

I was browsing through the sources and surprisingly, I found instructions for 
building on Windows. I thought I would play around with it. I've installed 
MSYS2 on a Windows VM, added development packages. I ran "./configure 
--enable-static-exe" and it succeeded. But make errors out quickly on DWORD.

Any suggestions on how to fix?
