Update.
1998-06-19 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/bits/sem.h: Don't define union semun. * sysdeps/unix/sysv/linux/bits/sem.h: Fix typo. * sysdeps/unix/sysv/linux/bits/ipc.h: Remove ipc_kludge definition here. * sysdeps/unix/sysv/linux/msgrcv.c (msgrcv): Add ipc_kludge definition here.
