Update.
2004-12-01  Jakub Jelinek  <jakub@redhat.com>

	* posix/tst-regex.c: Use defined _POSIX_CPUTIME && _POSIX_CPUTIME >= 0
	conditionals instead of defined _POSIX_CPUTIME.
	(main): If _POSIX_CPUTIME == 0, call sysconf to see if CPUTIME
	option is available.
	* posix/tst-regex.c2: Use defined _POSIX_CPUTIME && _POSIX_CPUTIME >= 0
	conditionals instead of defined _POSIX_CPUTIME.
	(do_test): If _POSIX_CPUTIME == 0, call sysconf to see if CPUTIME
	option is available.
	* sysdeps/posix/sysconf.c (__sysconf): If _POSIX_CPUTIME resp.
	_POSIX_THREAD_CPUTIME is defined to 0, return -1 for the corresponding
	_SC_ argument.
