1.7.1: no xdmcp login prompt after upgrade

[Paxton, Michael]

After upgrading to Cygwin/X 1.7.1, XDMCP query to any remote host no
longer produces a login prompt. All XDMCP connections functioned
correctly prior to upgrade.

Examination of an iptrace report (ipreport10.out) on the remote host
shows that Cygwin/X is not continuing the connection sequence after the
remote host replies to the initial port 177 communication.

To verify that X connectivity was still available on the remote host,
connection was attempted from another local system with Cygwin/X 1.5.25.
That connection functioned as expected, and its IP exchange was also
captured on the remote host as a benchmark. (An attempt to include that
traced was rejected by MAILER-DAEMON@sourceware.org).

Please advise as to any fix or workaround available. Alternately, please
advise as to the best way to revert to Cygwin/X 1.5.25.

Respectfully,
