Update.
	* locale/programs/ld-collate.c (collate_output): Don't start with empty
	extrapool and indirectpool obstacks since we need the offsets to be
	nonzero.
	(collate_read): Call load_locale, not find_locale.
	* locale/programs/ld-ctype.c (ctype_finish): If LC_CTYPE category
	wasn't defined in the file also initialize repertoire if possible.
	* locale/programs/ld-time.c (time_finish): Fix message string.
	* locale/programs/linereader.c: Cast parameters of lr_error to
	correct type to prevnet warning.
	* locale/programs/localedef.c (load_locale): New file.
	* locale/programs/localedef.h: Add its prototype.
	* locale/programs/repertoire.c (repertoire_new_char): Add missing
	parameters to lr_error call.

	* localedata/Makefile: Enable running tests again.
	* localedata/tests/test2.def: Adjust syntax to new specification.
	* localedata/tests/test3.def: Likewise.
	* localedata/tst-trans.sh: Redirect output of program into file.

	* string/strcoll.c: Fix many error in new implementation to make it
	pass (at least) the test suite.

	* locale/Makefile: Don't link localedef statically anymore.

	* locale/ld-collate.c (struct element_t): Add field is_character and
	use it to distinguish real character from collating elements and
	symbols.
	* locale/programs/ld-time.c: Likewise.
