	(libresolv-routines): Likewise.
	(distribute): Likewise.

	* resolv/gethnamaddr.c: Use thread safe resolver functions.
	* resolv/nss_dns/dns-host.c: Likewise.
	* resolv/nss_dns/dns-network.c: Likewise.

	* resolv/arpa/nameser.h: Update from Bind 8.2.2-P5.

	* resolv/Versions: Add __res_state and __res_ninit with version
	GLIBC_2.2 to libc.
	Add new interfaces with version GLIBC_2.2 to libresolv.

	* resolv/Banner: Update.

	* include/arpa/nameser_compat.h: New file.

	* resolv/ns_name.c: New file from Bind 8.2.2-P5.
	* resolv/ns_netint.c: Likewise.
