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.
