I do on my Cygwin box, and I copied /lib and /usr/include as Tim Renner's instructions
said.  Or am I supposed to cross-compile w32api?  Or did I not copy something I need?

Here's what I have in the way of directories under the top-level install dir
(cut down because the list is large):

I am mainly looking for what is missing in Tim Renner's instructions.
