Close AT_ENTRY case with `break'. * sysdeps/generic/strstr.c: New and much faster implementation by Stephen R. van den Berg. * sysdeps/generic/_strerror.c: _strerror_internal now takes three argument and has and explicit buffer length. * sysdeps/mach/_strerror.c: Change for new interface with three arguments. * stdio/perror.c, stdio/vfprintf.c: Callers changed. * sysdeps/mach/hurd/ttyname_r.c: New file. Reentrant version. * sysdeps/posix/ttyname_r.c: New file. Reentrant version. * sysdeps/stub/ttyname_r: New file. Define as dummy function. * sysdeps/posix/utimes.c: Include for prototype. (utimes): First parameter to utime must be file, not path. * sysdeps/posix/sysconf.c (__sysconf): Test for CLK_TCK in case _SC_CLK_TCK and return it when available. Test for STREAM_MAX in case _SC_STREAM_MAX and return it when available. Add case for _SC_2_LOCALEDEF which is now available. * posix/sys/types.h [__USE_SVID] (key_t): New type. * sysvipc/Makefile, sysvipc/ftok.c, sysvipc/sys/ipc.h, sysvipc/sys/msg.h, sysvipc/sys/sem.h, sysvipc/sys/shm.h, sysdeps/stub/sys/msq_buf.h, sysdeps/stub/sys/sem_buf.h, sysdeps/stub/sys/shm_buf.h, sysdeps/stub/sys/ipc_buf.h, sysdeps/stub/semctl.c, sysdeps/stub/semget.c, sysdeps/stub/semop.c, sysdeps/stub/shmat.c, sysdeps/stub/shmctl.c, sysdeps/stub/shmdt.c, sysdeps/stub/shmget.c, sysdeps/stub/msgctl.c, sysdeps/stub/msgget.c, sysdeps/stub/msgrcv.c, sysdeps/stub/msgsnd.c: New files.
