Extracting the key lines from the output, here's how to reproduce
the problem from the command line:

        $ mknod foo p
        $ src/mv --verbose foo /tmp
        `foo' -> `tmp/foo'
        src/mv: cannot create fifo `tmp/foo': Operation not permitted

Running the mv under ktrace/kdump shows:

  6257 mv       NAMI  "foo"
  6257 mv       RET   lstat 0
  6257 mv       CALL  lstat(0x300170,0xbffff8e0)
  6257 mv       NAMI  "/tmp/foo"
  6257 mv       RET   lstat -1 errno 2 No such file or directory
  6257 mv       CALL  rename(0xbffffe13,0x300170)
  6257 mv       NAMI  "foo"
  6257 mv       NAMI  "/tmp/foo"
  6257 mv       RET   rename -1 errno 18 Cross-device link
  6257 mv       CALL  unlink(0x300170)
  6257 mv       NAMI  "/tmp/foo"
  6257 mv       RET   unlink -1 errno 2 No such file or directory
  6257 mv       CALL  mknod(0x300170,0x1180,0)
  6257 mv       RET   mknod -1 errno 1 Operation not permitted

It appears that it attempts a rename, and when that fails, it tries
to do a mknod.   FWIW, the system-supplied /sbin/mknod command can only
make devices (it doesn't support the 'p' option), and the "man 2 mknod"
also refers only to creating device special files.

HAVE_MKFIFO is defined in  config.h.   It appears that the "mknod" command
is using mkfifo (and works), but the "mv" command only tries mknod.

I think that's the only remaining failure.  (At least the only one I
can consistently reproduce - I seem to be  seeing other failures that
show up in "make -k check" that don't show up when I re-run the
individual tests)
