Update.

	* elf/Makefile (tests): Add nodlopen.  Add rules to generate nodlopen.
	* include/dlfcn.h: Define __RTLD_DLOPEN.
	* elf/dl-load.c (_dl_map_object_from_fd): If DF_1_NOOPEN is set
	and this is a dlopen() call, do not load the binary.
	* dlfcn/dlopen.c: Add __RTLD_DLOPEN to mode passed down to _dl_open.
	* dlfcn/dlopenold.c: Likewise.
	* configure.in: Add test for -z nodelete option.
	* config.make.in: Define have-z-nodelete with libc_cv_z_nodelete.

	Make Hesiod NSS module thread-safe.

	* hesiod/README.hesiod: Update.

	* hesiod/Versions [GLIBC_2.2]: Add _nss_hesiod_getservbyport_r,
	_nss_hesiod_setprotoent, _nss_hesiod_endprotoent,
	_nss_hesiod_getprotobyname_r, and _nss_hesiod_getprotobynumber_r.
	* hesiod/Makefile (libnss_hesiod-routines): Add hesiod-init and
	hesiod-proto.
	* hesiod/nss_hesiod/hesiod-init.c: New file.
	* hesiod/nss_hesiod/hesiod-pwd.c: Rewritten for thread-safeness.

	* hesiod/nss_hesiod/hesiod-service.c
	(_nss_hesiod_getservbyport_r): New function.  Provide support for
	looking up services by port number.
	* hesiod/nss_hesiod/hesiod-proto.c: New file.

	* hesiod/hesiod.c: Update from BIND 8.2.3-T5B.
	* hesiod/hesiod.h: Likewise.
	* hesiod/hesiod_p.h: Likewise.

2000-07-20  Mark Kettenis  <kettenis@gnu.org>

	Fix problems with `struct __res_state' getting too big.
	* resolv/resolv.h (struct __sockaddr_in): New definition.
	(struct __res_state): Use __sockaddr_in instead of sockaddr_in in
	the private parts of the structure to save some space.
	* resolv/res_send.c (res_nsend): Cast &EXT(statp).nsaddrs[ns] to
	(struct sockaddr_in *) in call to sock_eq.
	Use memcpy to copy statp->nsaddr_list[ns] to &EXT(statp).nsaddrs[ns].
