Ulrich Drepper 880f421fc3 Update.
1998-02-16 17:33  Ulrich Drepper  <drepper@cygnus.com>

	* elf/rtld.c (dl_main): Recognize --library-path parameter and
	pass value (or NULL) to _dl_init_paths.
	* elf/dl-load.c (_dl_init_paths): Change to take one parameter,
	replacing local variable llp.  If llp is NULL examine LD_LIBRARY_PATH
	environment variable.
	* elf/link.h: Change prototype for _dl_init_paths.
	* elf/dl-support.c: Pass NULL in _dl_init_paths call.

	* localedata/Makefile (distribute): Add test files.

1998-02-17  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* localedata/tests/{test1.cm, test2.cm, test3.cm, test4.cm,
	test1.def, test2.def, test3.def, test4.def}: Simple input files
	for localedef. Contributed by Yung-Ching Hsiao
	<yhsiao@cae.wisc.edu>.

	* localedata/Makefile (tests): Call tst-locale.sh.

	* localedata/tst-locale.sh: New file, regression tests for some
	localedef problems.

	terminated.

	* locale/programs/ld-ctype.c (ctype_class_to): Silently ignore
	unknown characters and empty ranges.
	* locale/programs/ld-collate.c (collate_order_elem): When
	processing an ellipsis properly form a linked list in the result
	table, fix typo when allocating ordering array.
	[PR libc/419]

1998-02-13  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* elf/Makefile (ld-map): Define.
	(rtld-ldscript): Define.  Change all `$(objpfx)rtld-ldscript' to

	ld.so instead of environment variable.
