    d: Prefix object files from the root package with 'root-'
    
    None of the front-end module names in either the dmd or root package
    collide just yet, but that does not mean they won't in the future.
    
    gcc/d/ChangeLog:
    
            * Make-lang.in (D_FRONTEND_OBJS): Prefix object files from the root
            package with root-.
            (d/root-%.o): New recipe.
