Update.

2000-01-07  Andreas Jaeger  <aj@suse.de>

	Add support for Berkeley db 3.0.x and merge db support:
	* nss/nss_db/dummy-db.h (struct db30): New.
	(struct dbc30): New.
	Added DB30* flags.

	* nss/makedb.c: Move all database routines to db-open.c.
	(main): Adjust to interface changes.
	Load database early to initialize version dependend variables.

	* nss/db-open.c: Merge database routines from makedb.c.
	Define version dependend constansts as variables.
	(load_db): Check also for db 3.
	(internal_setent): Call dbopen.
	(db_cursor): New function from makedb; handles db 3 now.
	(dbopen): New function from makedb; handles db 3.

	* nss/nss_db/db-XXX.c: Use db_notfound since the value is
	different in different DB versions.

	* nss/nss_db/nss_db.h: Add version dependend constants as
	variables, add exportet interfaces from db-open.c.

	* nss/Makefile ($(objpfx)makedb): Link against db-open.

2000-01-07  Ulrich Drepper  <drepper@cygnus.com>

	* misc/error.c: Don't use `defined _LIBC', only `_LIBC'.
	Reported by Jim Meyering.

	* time/strftime.c: Pretty printing.

2000-01-07  Andreas Jaeger  <aj@suse.de>

	* manual/socket.texi (Host Names): Fix example.
	Reported by Marco Budde <budde@telos.de>.
