rm -f # no more args failure?

[Karl Berry]

Does anyone here use or know of an active system where plain
  rm -f
with no arguments fails? I mean, exits with bad status?

We are considering changing Automake to assume this works,
although we'd provide for a workaround just in case, something like
  make RM_F="rm -f nosuchfile"

But if there are still active systems where it's a problem,
we will probably make no change.

Thanks,
Karl
