commit 5641289a4647db43c0fdccee25da020ca04d03ad
Author: Jon Loeliger <jdl at freescale.com>
Date:   Tue Oct 23 09:28:54 2007 -0500

    DTC: Minor grammar rule shuffle.
    
    I like to see the basis cases established early in
    the rule sets, so place  "empty" reduction first.
    Purely cosmetic.
