Update.

1999-11-09  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-load.c (_dl_dst_count): Allow $ORIGIN to point to
	directory with the reference since this is as secure as using the
	object with the dependency.
	(_dl_dst_substitute): Likewise.

	* elf/dl-load.c (_dl_dst_count): Change strings in first two
	strncmp calls to allow reuse.
	(_dl_dst_substitute): Likewise.

1999-11-01  Arnold D. Robbins  <arnold@skeeve.com>

	* posix/regex.c (init_syntax_once): move below definition of
	ISALNUM etc., then use ISALNUM to init the table, so that
	the word ops will work if i18n'ed.
	(SYNTAX): And subscript with 0xFF for 8bit character sets.

1999-11-09  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/getlogin_r.c (getlogin_r): Sync with getlogin
	implementation for ttyname_r call; fix inverted condition; return
	ut_user.  Closes PR libc/1438.

1999-11-09  Ulrich Drepper  <drepper@cygnus.com>

	* timezone/checktab.awk: Update from tzcode1999h.
	* timezone/africa: Update from tzdata1999i.
	* timezone/asia: Likewise.
	* timezone/australasia: Likewise.
	* timezone/backward: Likewise.
	* timezone/europe: Likewise.
	* timezone/northamerica: Likewise.
	* timezone/southamerica: Likewise.
	* timezone/iso3166.tab: Likewise.
	* timezone/zone.tab: Likewise.

	* sysdeps/unix/sysv/linux/bits/resource.h: Define values also as
	macros.  Patch by brg@csua.berkeley.edu [PR libc/1439].

1999-11-09  Andreas Jaeger  <aj@suse.de>

	* posix/Makefile (tests): Added tst-getlogin.

	* posix/tst-getlogin.c: New file, contains simple tests for
	getlogin and getlogin_r.

1999-11-09  Andreas Schwab  <schwab@suse.de>

	* misc/syslog.c: For LOG_PERROR only append a newline if
	necessary.

-# * All data in Shanks are correct through 1990.  In particular,

-# * Areas where Shanks reports DST up to 1990, but the IATA reports no DST
-#   in 1995, stopped observing DST in mid-1990.
-#
-# Under these assumptions Brazil needs 7 entries to cover all the distinct

-# Noronha (UTC-2), Fortaleza (UTC-3), and Manaus (UTC-4) stopped observing DST
