# 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.
