Subject: Update.

2001-12-18  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/sparc/sparc64/clone.S (clone): Subtract
	stack bias from child stack pointer before passing it to clone syscall.

2001-12-18  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/posix/sysconf.c (__sysconf): Respect POSIX minimum for
	_SC_TZNAME_MAX.
	* sysdeps/generic/sysconf.c (__sysconf): Likewise.
	Reported by Thorsten Kukuk <kukuk@suse.de>.

	* sysdeps/unix/grantpt.c (grantpt): Correct typo in comment and
	add some casts.

	* sysdeps/unix/sysv/linux/grantpt.c: Make __unix_grantpt static.

2001-12-18  Thorsten Kukuk  <kukuk@suse.de>

	* sysdeps/unix/sysv/linux/grantpt.c: Make errno results standard
	conforming: return EBADF if file descriptor is invalid and EINVAL
	if file descriptor is no valid tty.
	* login/tst-grantpt.c: New file.
	* login/Makefile (tests): Add tst-grantpt.
