I'm responsible for that "cygwin" version, so I'll work with you to  
debug this if you want.  Did you get to this failure by using my zip  
file and following the instructions on:

Binaries#head-735c03f140af5a704e05887acfa44ea0b9b43146

I think it looks for an environment variable named "HOME", or  
possible the Windowsy equivalent USERPROFILE.

That would be ideal.

Nope.  I spent a couple of hours trying to port it once.  The  
problems I hit were all of the familiar form "check for platform type  
and then configure a bunch of settings for that platform instead of  
testing each capability separately to see if it works".  This  
familiar pattern fails when the "platform type" is 'windowsy', but it  
actually provides a bunch of unix functions that normal Windows  
doesn't provide.

No!  Use darcs on cygwin, and help me and Salvatore make it work better.
