* mach/Machrules: Use -include for $(*.ir). * hurd/hurd/ioctl.h (_HURD_HANDLE_IOCTLS): Mask off type bits in request values. * sysdeps/mach/hurd/ioctls.h (_IOC_NOTYPE): New macro. (_IOT_COUNT2): Field is 3 bits, not 2. * sysdeps/mach/hurd/ioctl.c: Ignore handler if it fails with ENOTTY. * hurd/hurdioctl.c (_hurd_lookup_ioctl_handler): Mask off type bits before looking up handler. (fioctl): Use __hurd_dfail. (fioctl, fioclex): Use ENOTTY for bogus request instead of EGRATUITOUS. Wed Feb 14 00:21:17 1996 David Mosberger-Tang <davidm@azstarnet.com> * sysdeps/alpha/memchr.c (memchr): loop searching for matching character bailed out one too early; changed constant 6 to 7 to fix this.
