glibc/rt/tst-aio4.c
Andreas Jaeger 207390f763 Update.
2001-06-11  Michael Deutschmann <michael@talamasca.ocis.net>

	* rt/tst-aio4.c (do_test): Test whether rt signals are supported.
	Use my_signo instead of MY_SIGNO and initialize it so that the
	used signal is always available.

2001-06-11  Andreas Jaeger  <aj@suse.de>, 
	    Michael Deutschmann <michael@talamasca.ocis.net>

	* io/test-lfs.c (do_prepare): Clean up error messages.
	(test_ftello): Check for EFBIG and ENOSP, clean up error messages.
	(do_test): Likewise.

2001-06-11  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/sysv/linux/powerpc/bits/termios.h (IXANY, IUCLC,
	IMAXBEL): Make always visible since they're needed by POSIX.
	Closes PR libc/2320, reported by Chris Yeoh <cyeoh@samba.org>.

2001-06-10  Ben Collins  <bcollins@debian.org>

	* sysdeps/arm/elf/start.S: Use #function, not @function, for
	.type of _start.

	* sysdeps/ieee754/ldbl-128/s_ilogbl.c: Include limits.h to get
	INT_MAX.

2001-06-07  H.J. Lu  <hjl@gnu.org>

	* sunrpc/rpc/rpc.h: Add __BEGIN_DECLS/__END_DECLS.
