	* 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.
