Update.
2004-04-16 Jakub Jelinek <jakub@redhat.com> * misc/syslog.c (vsyslog): Avoid freeing failbuf. 2004-04-15 Jakub Jelinek <jakub@redhat.com> * rt/Makefile (tests): Add tst-timer4. * rt/tst-timer4.c: New test. 2004-04-15 Jakub Jelinek <jakub@redhat.com> * rt/tst-mqueue5.c (rtmin_code): New variable. (rtmin_handler): Set it. (thr, do_child, do_test): Also check rtmin_code. 2004-04-14 Jakub Jelinek <jakub@redhat.com> * rt/Makefile (tests): Add tst-mqueue7. (tst-mqueue7-ARGS): Set. * rt/tst-mqueue7.c: New test. 2004-04-13 Jakub Jelinek <jakub@redhat.com> * rt/Makefile (tests): Add tst-mqueue5 and tst-mqueue6. * rt/tst-mqueue1.c (do_one_test): Bitwise or check_attrs () into result instead of replacing it. Use TEMP_FAILURE_RETRY around waitpid, kill child if waitpid failed. (do_test): Bitwise or check_attrs () into result instead of replacing it. Change temp mq name. * rt/tst-mqueue5.c: New test. * rt/tst-mqueue6.c: New test. * rt/tst-mqueue.h: Include stdio.h, unistd.h, sys/uio.h. (temp_mq_list, delete_temp_mqs): Remove. (temp_mq_fd): New variable. (do_cleanup, do_prepare): New functions. (add_temp_mq): Rewritten to use a temp file. (PREPARE): Define. (CLEANUP_HANDLER): Change to do_cleanup (). * rt/tst-timer3.c: Don't fail if _POSIX_THREADS is not available. 2004-04-13 Thorsten Kukuk <kukuk@suse.de> * sysdeps/s390/ffs.c: Include limits.h 2004-04-13 Kaz Kojima <kkojima@rr.iij4u.or.jp> * sysdeps/unix/sysv/linux/sh/sysdep.h (SUBSTITUTE_ARGS_1, SUBSTITUTE_ARGS_2, SUBSTITUTE_ARGS_3, SUBSTITUTE_ARGS_4, SUBSTITUTE_ARGS_5, SUBSTITUTE_ARGS_6, SUBSTITUTE_ARGS_7): Load argument values into temporary variables.
