From 07672d4e0ae887d4b06bdd01b03bbe64e8163bdf Mon Sep 17 00:00:00 2001

Subject: [PATCH] Skip setsockopt(SO_REUSEADDR) for the Unix-domain postmaster
 socket on all platforms, not just SCO.  The operation is undefined for
 Unix-domain sockets anyway.  It seems SCO is not the only platform that
 complains instead of treating the call as a no-op.
