2001-03-04 Bruno Haible <bruno@clisp.org> * intl/dcigettext.c (DCIGETTEXT): Increment path_max proportionally. 2001-10-31 Bruno Haible <bruno@clisp.org> * intl/plural.y: Include <stddef.h>, needed for NULL with SunOS 4 cc. 2001-03-21 Bruno Haible <bruno@clisp.org> * intl/dcigettext.c (_nl_state_lock): Mark as #ifdef _LIBC. AIX 3 xlc chokes on empty macro arguments. * intl/plural.y: Add #pragma for alloca on AIX 3. 2001-11-27 Ulrich Drepper <drepper@redhat.com> * intl/dcigettext.c (guess_category_value): Only implement for glibc. Otherwise rely on function _nl_locale_name which isn't present in the glibc sources. 2001-09-24 Bruno Haible <bruno@clisp.org> * intl/loadmsgcat.c (_nl_init_domain_conv): Also enable transliteration when building on a glibc system but outside glibc. 2001-09-22 Bruno Haible <bruno@clisp.org> * intl/plural-eval.c: New file, extracted from dcigettext.c. * intl/dcigettext.c (plural_eval): Remove function, moved to intl/plural-eval.c. (plural_lookup): Call PLURAL_EVAL instead of plural_eval. Include plural-eval.c. 2001-09-22 Bruno Haible <bruno@clisp.org> * intl/plural-exp.c (EXTRACT_PLURAL_EXPRESSION): Reject numbers that don't start with a digit; nplurals must be positive. 2001-09-02 Bruno Haible <bruno@clisp.org> * intl/plural-exp.h: New file, extracted from gettextP.h. * intl/plural-exp.c: New file, extracted from loadmsgcat.c. * intl/gettextP.h (struct expression, struct parse_args, __gettext_free_exp, __gettextparse): Move to plural-exp.h. * intl/loadmsgcat.c: Include plural-exp.h. (PLURAL_PARSE): Move macro to plural-exp.h. (plvar, plone, germanic_plural, INIT_GERMANIC_PLURAL): Move to plural-exp.c. (_nl_load_domain): Move plural handling code to plural-exp.c. Call EXTRACT_PLURAL_EXPRESSION. (_nl_unload_domain): Update. * intl/dcigettext.c: Include plural-exp.h. * intl/plural.y: Include plural-exp.h, not gettextP.h. (FREE_EXPRESSION): Move macro to plural-exp.h. * intl/Makefile (routines): Add plural-exp. (distribute): Add plural-exp.h. 2001-07-28 Bruno Haible <bruno@clisp.org> * intl/l10nflist.c (_nl_normalize_codeset): Cast isalnum, isalpha, isdigit, tolower argument to 'unsigned char'. * intl/loadmsgcat.c (_nl_load_domain): Cast isspace argument to 'unsigned char'. * intl/localealias.c (read_alias_file): Cast isspace argument to 'unsigned char'. 2001-10-20 Bruno Haible <bruno@clisp.org> Assume strchr() exists. (Without it, intl/explodename.c wouldn't link anyway.) * intl/dcigettext.c (strchr): Remove fallback definition; it conflicts with the variable 'index' in plural_lookup. * intl/l10nflist.c (strchr): Likewise. * intl/localealias.c (strchr): Likewise. Assume <stddef.h>, <stdlib.h>, <string.h>, <locale.h> exist. * intl/bindtextdom.c: Likewise. * intl/dcigettext.c: Likewise. * intl/dgettext.c: Likewise. * intl/dngettext.c: Likewise. * intl/explodename.c: Likewise. * intl/finddomain.c: Likewise. * intl/gettext.c: Likewise. * intl/l10nflist.c: Likewise. * intl/loadmsgcat.c: Likewise. * intl/localealias.c: Likewise. * intl/ngettext.c: Likewise. * intl/textdomain.c: Likewise. * intl/gettext.h: Assume <limits.h> exists.
