+
+ * sysdeps/unix/sysv/linux/bits/in.h (IPV6_JOIN_GROUP,
+ IPV6_LEAVE_GROUP): New names for IPV6_ADD_MEMBERSHIP,
+ IPV6_DROP_MEMBERSHIP.
+ * sysdeps/generic/bits/in.h (IPV6_JOIN_GROUP, IPV6_LEAVE_GROUP):
+ Likewise.

+ Reported by Reinhard Moosauer <RMoosauer@steinecker.com>.
+
+2000-04-10 Jes Sorensen <Jes.Sorensen@cern.ch>
