Trimurthi,
The cygwin mailing list is the proper place for such inquiries. It is
strongly discouraged to send personal mail with such requests, and they
will, in general, be ignored. I've forwarded this request to the proper
mailing list, and reset the Reply-to: field accordingly for your
convenience.
