Update.
2000-04-11  Ulrich Drepper  <drepper@redhat.com>

	* posix/globtest.sh: Fix last change.

2000-04-10  Philip Blundell  <philb@gnu.org>

	* sysdeps/unix/sysv/linux/bits/in.h (IPV6_JOIN_GROUP,
	IPV6_LEAVE_GROUP): New names for IPV6_ADD_MEMBERSHIP,
	IPV6_DROP_MEMBERSHIP.
	* sysdeps/generic/bits/in.h (IPV6_JOIN_GROUP, IPV6_LEAVE_GROUP):
	Likewise.

2000-04-11  Ulrich Drepper  <drepper@redhat.com>

	* elf/readlib (process_file): Close streams in case of an error.

2000-04-09  Andreas Jaeger  <aj@suse.de>

	* elf/readlib.c (process_file): Check if file is big enough to
	contain aout and ELF headers.
	Reported by Reinhard Moosauer <RMoosauer@steinecker.com>.

2000-04-10  Jes Sorensen  <Jes.Sorensen@cern.ch>

	* elf/dl-fini.c: Include alloca.h to get proper prototype for alloca().

2000-04-11  Ulrich Drepper  <drepper@redhat.com>

	* test-skeleton.c (main): If STDOUT_UNBUFFERED is defined, make stdout
	stream unbuffered.
	* rt/Makefile (tests): Add tst-clock.
	Add rules to build tst-clock.
	* rt/tst-clock.c: New file.
	* sysdeps/unix/i386/i586/clock_getres.c: Correct expression to decide
	about initialization of nsec.
	* sysdeps/unix/i386/i586/clock_gettime.c: Correct expression to decide
	about initialization of freq.  Set retval to zero if successful.
	* sysdeps/unix/sysv/linux/i386/get_clockfreq.c: Cache result.
