Here's a method that I have used successfully:

- Build your Cygwin DLL. Whether you build the DLL with dlltool, dllwrap, or
libtool, a .def file should be produced in the process.

- Use MSVC's command line tool "lib" with the /def option and your .def file
to generate an MSVC-style .lib import library.

- Link your MSVC project with the .lib import library.
