Update.

2000-07-28  Ulrich Drepper  <drepper@redhat.com>

	* stdio-common/_i18n_itoa.c: Removed.
	* stdio-common/_i18n_itoa.h: Removed.
	* stdio-common/_i18n_itowa.c: Removed.
	* stdio-common/_i18n_itowa.h: Removed.
	* stdio-common/_i18n_number.h: New file.
	* stdio-common/Depend: New file.
	* stdio-common/printf-parse.h: Handle I modifier correctly.  Optimize.
	* stdio-common/vfprintf.c: Rewrite buffer handling for integer
	printing.  Change printing of numbers with locale specific digits to
	use new code in _i18n_number.h.

	* stdio-common/bug13.c: Improve messages.

	* locale/programs/ld-ctype.c (ctype_read): Improve error message.
	(set_class_defaults): Always search also for Uxxxx names.
	Detect insufficient number of outdigits.

	* locale/Makefile (C-translit.h): Use mv not $(move-if-changed).
