Update.

2002-12-28  Ulrich Drepper  <drepper@redhat.com>

	* descr.h (struct pthread): Move header.data.list to the back of the
	struct.
	* sysdeps/i386/tls.h (tcbhead_t): Move list to the back of the struct.
	(MULTIPLE_THREADS_OFFSET): Adjust offset.
	(SYSINFO_OFFSEET): Likewise.

2002-12-27  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/i386/i686/dl-sysdep.h (USE_DL_SYSINFO):
	Define.
	(DL_SYSINFO_DEFAULT): Cast to uintptr_t to avoid warnings.
	* sysdeps/unix/sysv/linux/i386/dl-sysdep.h (NEED_DL_SYSINFO,
	DL_SYSINFO_DEFAULT, DL_SYSINFO_IMPLEMENTATION): Define.
	(USE_DL_SYSINFO): Undef.

2002-12-22  Jakub Jelinek  <jakub@redhat.com>

	* Makefile (tests-reverse): Use $(objpfx)../libc.so instead of
	$(common-objpfx)libc.so.
	* tst-cancel4.c (tf_write, tf_writev): Increase buf sizes so that
	it is bigger than pipe buffer size even on arches with bigger
	page size.
	(tf_usleep): Cast usleep argument to useconds_t to avoid warnings.
