Yes. I spent a few cents and a few hours wrestling with it. AFAICT your 
are hosed on 64bit Windows. I can't get flex built and Cygwin is 
behaving very oddly. There are indications that the problem could be 
fairly deep - see 
<http://www.mail-archive.com/cygwin@cygwin.com/msg102463.html>

I can try again with Cygwin 1.7. and see if that improves matters, but I 
bet it doesn't.
