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.
