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.
