Update.

2004-01-05  Jakub Jelinek  <jakub@redhat.com>

	* posix/regcomp.c (regcomp): Fix comment typo.
	(regfree): Free preg->translate, clear buffer, allocated, fastmap
	and translate fields.

	* posix/regcomp.c (build_charclass, buld_charclass_op): Change first
	argument to unsigned RE_TRANSLATE_TYPE.
	* posix/regex_internal.h (re_string_t): Change trans type to
	unsigned RE_TRANSLATE_TYPE.
	* posix/regex_internal.c (re_string_construct_common): Cast
	trans to unsigned RE_TRANSLATE_TYPE.
	(re_string_peek_byte_case, re_string_fetch_byte_case): Avoid fast
	path if pstr->trans.  Never translate the character through
	pstr->trans.
	* posix/Makefile (tests): Add bug-regex22.
	(bug-regex22-ENV): Set.
	* posix/bug-regex22.c: New test.
