  We show that regularizing divergent integrals is crucially important when
applied to the loop diagrams corresponding to quantum corrections to the
coupling of the ``gravitational" scalar field due to the interaction among
matter fields. We use the method of continuous spacetime dimensions to
demonstrate that WEP is a robust property of the Brans-Dicke theory beyond the
classical level, hence correcting our previous assertion of the contrary. The
same technique can be used to yield the violation of WEP when applied to the
scale-invariant theory, thus providing another reason for expecting fifth-
force-type phenomena.
