Update.
2000-10-24 Paul Eggert <eggert@twinsun.com> * time/strftime.c (my_strftime macro) [!defined _LIBC && HAVE_TZNAME && HAVE_TZSET]: When redefining, do it without args, so that it works even if emacs is defined and an extra argument is passed to my_stftime. (my_strftime function): When evaluating a subformat, pass ut_argument as well. 2000-10-24 Andreas Schwab <schwab@suse.de> * sysdeps/unix/sysv/linux/ia64/Versions: Add pciconfig_read and pciconfig_write. * sysdeps/generic/dl-cache.c (_dl_cache_verify_ptr): Correct test for files with new cache format. (_dl_load_cache_lookup): Add variable cache_data_size for size of the data. Correctly report error if neither old not new signature is found. Little optimizations. Mostly based on a patch by Denis Zaitsev <zzz@cd-club.ru>.
