Update.
1999-12-21 Shinya Hanataka <hanataka@abyss.rim.or.jp> * locale/lc-time.c: Extend structure era_entry. * locale/localeinfo.h: Likewise. * locale/lc-time.c: Handle '-' direction used in locale's era part properly. * time/strptime.c: Likewise. * time/strftime.c: Likewise. * locale/programs/ld-time.c: Consider negative values in era part of locale as B.C.. * time/strptime.c (strptime_internal): Merged Yoshiyama's %E[CyY] implementation. 1999-12-21 Akira Yoshiyama <yosshy@debian.or.jp> * time/strptime.c (strptime_internal): Fix segV bugs of a couple of recursive() call. * time/strptime.c (strptime_internal): Implement `%EC',`%Ey',`%EY' parsing. 1999-12-21 Ulrich Drepper <drepper@cygnus.com> * sysdeps/arm/dl-machine.c (CLEAR_CACHE): Fix a2 value.
