I've just tested this -- the clone is failing as expected with the
current cygwin package from setup-x86.exe, and working just fine with
the 2014-01-28 snapshot.  I've not tested the snapshot on x86_64, but I
can try to find time to do that if it'd be useful.

I have to say, I'm really impressed with your debugging here!
