Copying the Cygwin DLLs to directories other than those to which they
were installed is _highly_ discouraged.  You're using a non-standard
installation which means you're basically "on your own" as far as this
list is concerned.  This list can really only respond to problems with
standard installations, given the shear number of variables in the non-
standard cases.

Perhaps trying the same thing with Cygwin ssh/sftp would provide you some
insight?
