	* nss/nss_db/dummy-db.h (struct db24): Add missing field flags.
	(struct db27): Add missing fields byteswapped, join and flags;
	remove wrong member handleq.
	(struct dbc27): Correct lock field.

	* nss/makedb.c: Remove __P.

2000-01-04  Andreas Jaeger  <aj@suse.de>

	* nss/nss_db/db-open.c (internal_setent): Check for db_open for
	success, fix a memory leak and clean up function.

2000-01-04  Ulrich Drepper  <drepper@cygnus.com>

	* Makefile (install): Pass $(install_root) to ldconfig.
	Patch by Akira YOSHIYAMA <yosshy@tkf.att.ne.jp>.

2000-01-03  Jakub Jelinek  <jakub@redhat.com>

	* soft-fp/op-1.h: Fix division for machines using not normalizing
	version of udiv_qrnnd in longlong.h.
	* soft-fp/sysdeps/mips/sfp-machine.h: Likewise.
	* soft-fp/sysdeps/mips/mips64/sfp-machine.h: Likewise.
	* soft-fp/sysdeps/sparc/sparc64/sfp-machine.h: Likewise.
	Patch by Eddie C. Dost <ecd@skynet.be>.

	* soft-fp/soft-fp.h (QItype, UQItype): New types used by longlong.h.

2000-01-03  Andreas Schwab  <schwab@suse.de>

	* sysdeps/generic/dl-sysdep.c: Initialize __libc_multiple_libcs,
	needed for change in common symbol handing in newer binutils.
