I am having issues linking this on cygwin.

If I install the binary package (4.3), it won't load:

And then there's this:

I had a similar issue before, and it was solved by tweaking Makevars.
Hope there's an easy fix for this as well. Any ideas?
Seems like pasting with backticks messed up the formatting, but I'm posting anyways.

If you have a patch that is not affecting other builds I would be happy to consider. I don't know much about cygwin, so not sure I can be of any help.
