Unfortunately, thats just the start of the fun on windows.  There are
a few code changes needed to support windows as well.

I have ported the latest FFI code to windows, but building it is a bit
involved - you need msys+mingw, you need to build ruby from source
(matching the one-click version) using mingw, and then build the FFI
gem using that new ruby install.

Hopefully, there will be binary gems available for ruby-ffi 0.3.0

JRuby already contains FFI - no need to install anything more, and is
possibly the least painful way of using it on windows.
