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.
