I don't think that's the concern here - it's more a matter of whether
the target, and DejaGNU, support this.  Lots of embedded targets seem
to have trouble with it.  Take a look at "noargs" in the DejaGNU board
files for a couple of examples, IIRC.  GDB jumps through some hoops to
test this, and gets it wrong in a bunch of places too.
