From Visual Studio, set the project type to be a relocable library
(DLL).  I ended up hand-editing its .def file to list the exportable
functions; for some reason __cdecl did not work for me.

I used dlltools to load the DLL at runtime; see this older mailing list
post:

http://cygwin.com/ml/cygwin/2002-08/msg01141.html

Now if you're referring to linking to the DLL at compile time, see
http://cygwin.com/cygwin-ug-net/dll.html#DLL-LINK.  Note that I have not
personally done this yet; I have only built and used relocatable MSVC
DLLs.

I've also built and used relocatable Cygwin DLLs, but gave up after
this:  http://cygwin.com/ml/cygwin/2002-08/msg01002.html, with a
follow-up at http://cygwin.com/ml/cygwin/2002-08/msg01046.html.
