Update.
2000-05-06 Bruno Haible <haible@clisp.cons.org> * iconv/gconv_open.c (__gconv_open): If __gconv_find_transform returned != __GCONV_OK, there is nothing to clean up. 2000-05-06 Bruno Haible <haible@clisp.cons.org> * intl/tst-gettext.c (main): Disable possibly existing LC_CTYPE and OUTPUT_CHARSET environment variables. 2000-05-06 Andreas Jaeger <aj@suse.de> * sysdeps/generic/dl-cache.h (struct file_entry_new): New. (struct cache_file_new): New. (struct file_entry): New (moved from cache.c). (struct cache_file): New (moved from cache.c). * sysdeps/generic/dl-cache.c (SEARCH_CACHE): New macro, broken out from _dl_load_cache_lookup. (_dl_load_cache_lookup): Move search to SEARCH_CACHE macro, handle the different cache formats. New variable cache_new for new format. * elf/ldconfig.h: Change according to changes in cache.c and ldconfig.c; remove cache_libcmp; add opt_format. * elf/ldconfig.c: Include "dl-cache.h" and "dl-procinfo.h"; remove stuff that's defined in those headers. Add hwcap to struct lib_entry. (opt_format): New variable to select cache format. (options): Add format parameter. (is_hwcap): New function. (path_hwcap): New function. (parse_opt): Handle new format parameter. (search_dir): Handle hwcap, search also subdirectories with hwcap. * elf/cache.c (_GNU_SOURCE): Removed. Not needed anymore since ldconfig is part of glibc. Include dl-cache.h and remove stuff that's defined there. (struct cache_entry): Add new member hwcap. (print_entry): Print hwcap, cleanup a bit. (print_cache): Print new and old formats. (compare): Use _dl_cache_libcmp from dl-cache.h; handle hwcap. (save_cache): Save new and old formats. (add_to_cache): Handle hwcap. * sysdeps/generic/dl-cache.c (_dl_cache_libcmp): Moved from here... * sysdeps/generic/dl-cache.h (_dl_cache_libcmp): ...to here. * sysdeps/generic/dl-cache.c (LD_SO_CACHE): Moved from here... * sysdeps/generic/dl-cache.h (LD_SO_CACHE): ...to here. * sysdeps/generic/dl-cache.c (CACHEMAGIC): Moved from here... * sysdeps/generic/dl-cache.h (CACHEMAGIC): ...to here. 2000-05-05 Bruno Haible <haible@clisp.cons.org> * intl/dcigettext.c (alignof): New macro. (_nl_find_msg): Use it instead of __alignof__. Pass correct output buffer length to __gconv/iconv. If malloc (freemem_size) fails, set freemem_size to 0. 2000-05-05 Bruno Haible <haible@clisp.cons.org> * intl/dcigettext.c (dcigettext): Fix interpretation of tsearch return value.
