Update

2001-01-04  H.J. Lu  <hjl@gnu.org>

	* elf/dl-support.c (DL_FIND_AUXV): New.  Defined if not defined.
	(_dl_clktck): Declared.
	(non_dynamic_init): Take 3 arguments.
	Set _dl_pagesize, _dl_platform and _dl_clktck from AUX.

2001-01-01  Bruno Haible  <haible@clisp.cons.org>

	Finish implementation of plural form handling.
	* intl/dcigettext.c (known_translation_t): Rename 'domain' field to
	'domainname'.  Remove 'plindex' field. Add 'domain' and
	'translation_length' fields.
	(transcmp): Don't compare 'plindex' fields.
	(plural_lookup): New function.
	(DCIGETTEXT): Change cache handing in the plural case.  Don't call
	plural_eval before the translation and its catalog file have been
	found. Remove plindex from cache key.  Add 'translation_length' and
	'domain' to cache result.
	(_nl_find_msg): Remove index argument, return length of translation
	to the caller instead.  Weaken comparison of string lengths, to account
	for plural entries.  Call iconv() on the entire result string, not
	only on the portion needed so far.
	* intl/loadinfo.h (_nl_find_msg): Remove index argument, add lengthp
	argument.
	* intl/loadmsgcat.c (_nl_load_domain): Adapt to _nl_find_msg change.
