+# Subject: sockets broken under IRIX 5.3? YES...how to fix
+# Anyone attempting to use perl4 or perl5 with SGI IRIX 5.3 may discover
+# that sockets are essentially broken. The syslog interface for perl also
+# fails because it uses the broken socket interface. This problem was
+# reported to SGI as bug #255347 and it can be fixed by installing
+# patchSG0000596. The patch can be downloaded from Advantage OnLine (SGI's
+# WWW server) or from the Support Advantage 9/95 Patch CDROM. Thanks to Tom
+# Christiansen and others who provided assistance.
