+	Fixed more IPv6 portability problems.
+	* configure.in: Check for freehostent.
+	* src/intern.h: Require HAVE_FREEHOSTENT to be defined if we are
+	to use getipnodebyname.
+	* src/isc_udp.c (isc_mkudpaddress): Don't call freehostent()
+	unless hp has been allocated by getipnodebyname().
+	* src/isc_tcp.c (isc_mktcpaddress): Don't call freehostent()
+	unless hp has been allocated by getipnodebyname().
+	* src/isc_socket.c (isc_getipnum): Fixed typo: strncpy was spelled
+	"strncopy".
