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).
