The static library.

The import library for the DLL.

The DLL.

Probably easiest if you use the MinGW/MSYS environment.  It should be
possible to "cross-compile" this from a Cygwin setup by passing
  --host=i386-pc-mingw CFLAGS=-mno-cygwin CXXFLAGS=-mno-cygwin ...

I don't recall the exact value for host, nor whether it was necessary
in any case, and may have forgotten other minor details.  I've mostly
just used MinGW itself for compiling stand- alone libraries.

The MinGW home page has a nice FAQ:
http://www.mingw.org/MinGWiki/index.php/FAQ

(There is also good information about this from Cygwin; I can't find it
right now.)

Cheers,
Ralf
