+Add symbol versioning to the public LDAP libraries.  This is required for
+library transitions, such as the current transition from 2.1 to 2.4,
+since programs will sometimes have both libraries loaded by different
+dependency chains during the transition.
+
+Not yet contributed upstream.
+
+Upstream ITS #5365 filed requesting symbol versioning for libldap and
+libber.
