Update.

1998-03-12 13:11  Tim Waugh  <tim@cyberelk.demon.co.uk>

	* posix/wordexp-test.c: More tests.
	(main): Set up arena for pathname expansion tests (in a temporary
	directory).
	(testit): Don't check word count or word vector if return value is
	non-zero.

	* posix/wordexp.c (exec_comm): Always chop off terminating
	linefeed (just like bash does).
	(parse_param): Change lots of occurrences of "if (!*env)" to "if
	(!env || !*env)".
	(parse_param): For assignment inside parameter expansion, use all
	expanded words in assignment rather than just the first.
	(parse_param): Corrected return value for parameter expansion of
	an unset variable when WRDE_UNDEF is in effect.
	(parse_dollars): Don't field-split if quoted.
	(wordexp): Opening brace character isn't allowed unquoted.

1998-03-12  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dlerror.c: Fix concurrency problems with error string and
	number.

	* elf/dl-deps.c (_dl_map_object_deps): Print debug info when
	filter/auxiliary are being loaded.

1998-03-12 14:24  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dlerror.c (last_object_name): Removed.
	(dlerror): Don't use last_object_name.
	(_dl_error_run): Omit second argument to _dl_catch_error.
	* elf/dl-error.c (struct catch): Remove objname member.
	(_dl_signal_error): Construct string including objname when given.
	(_dl_catch_error): Remove objname handling.
	* elf/link.h (_dl_catch_error): Fix prototype and comment.
	* elf/rtld.c (dl_main): Call _dl_catch_error correctly.
	* elf/dl-deps.c (_dl_map_objet_deps): Likewise.
	* nss/nsswitch.c (nss_dlerror_run): Likewise.
	* iconv/gconv_dl.c (dlerror_run): Likewise.
	[Corrects PR libc/501].
