+Add hooks to compile contrib/wrt/dhcp_release.c. This utility is used to
+send a DHCPRELEASE message to tell the local DHCP server to delete a
+particular lease.
+
+Solaris doesn't support AF_NETLINK, so use getifaddrs() to determine the
+IP address of an interface on which Dnsmasq process is listening.
+
+This patch was developed in-house. Since it is Solaris-specific it is not
+suitable for upstream.
