Update.
* posix/runtests.c (main): Don't use exit() to avoid warning with broken compilers. * string/bug-strncat1.c: Undefine __USE_STRING_INLINES before defining it again to avoid warning. * string/bug-strpbrk1.c: Likewise. * string/bug-strspn1.c: Likewise. 2000-10-29 Bruno Haible <haible@clisp.cons.org> * locale/C-translit.h.in: Include more rules from translit_neutral. Remove a few German and Danish specific rules. * locale/gen-translit.pl: Avoid an error when printing a string containing a '%' character. * locale/C-translit.h: Regenerated. * intl/translit.po: Choose different translations. * intl/tst-translit.c: Update. 2000-10-29 Bruno Haible <haible@clisp.cons.org> * locale/programs/ld-ctype.c (translit_include_t): New type. (locale_ctype_t): Remove translit_copy_locale, translit_copy_repertoire fields, add translit_include field. (ctype_read): After seeing "translit_start" in ignore_content mode, skip the entire translit section, not only one line. Remove dead test for tok_translit_end. Enqueue include statements into a list. Signal error if tok_eof seen before tok_translit_end. (translit_flatten): New function. (allocate_arrays): Call translit_flatten. 2000-10-30 Ulrich Drepper <drepper@redhat.com>
