Alright,
I ended up doing a bit more of playing with this. Looks like skipping
Cygwin and interacting directly with Win32, just like it's done under

I don't like the following patch one bit, though. The include doesn't seem
to belong here, and I think dlopen()/dladdr() code should work under Cygwin.
