Update.

2000-09-29  Ulrich Drepper  <drepper@redhat.com>

	* elf/chroot_canon.c: Don't report a failure if the last path
	component is not available.
	* elf/ldconfig.c (parse_conf): Use canonicalized name when reporting
	error.

	* elf/cache.c (print_cache): Use stat64 instead of stat.
	* elf/ldconfig.c (chroot_stat): Likewise.
	(create_links): Likewise.
	(manual_link): Likewise.
	(search_dir): Likewise.
	* elf/readlib.c (process_file): Likewise.

	* Makefile (install): Set LC_ALL and LANGUAGE to C before running
	ldconfig.

2000-09-29  Jakub Jelinek  <jakub@redhat.com>

	* elf/chroot_canon.c: New file.
	* elf/Makefile: Build and distribute it.
	* elf/ldconfig.h (process_file): Add real_file_name argument.
	(chroot_canon): Add prototype.
	* elf/ldconfig.c (cache_file): Remove const.
	(chroot_stat): New.
	(create_links): Add real_path argument.
	If opt_chroot, maintain both real and given filenames.
	(manual_link): Likewise.
	(search_dir): Likewise.
	(parse_conf): If opt_chroot, use chroot_canon to find the real
	config file.
	(main): For -r, try to use chroot, if it fails, leave opt_chroot set
	and use chroot_canon where appropriate to do the same as if chroot
	succeeded.
	* elf/readlib.c (process_file): Add real_file_name argument, pass it
	to fopen.

2000-09-29  Ulrich Drepper  <drepper@redhat.com>

	* math/complex.h (_Complex): We can be more specific when _Complex
	is defined by the compiler.
