Is the following an acceptable approach? I specifically am trying
to avoid duplicating all of the function names and the infrastructure for
creating the correct defines, config cache, etc. That seems to force me
to insert the additional test into the existing test function definitions.
Note, this is a PRELIMINARY patch. I have not moved the
definitions and tests so that the context diff more clearly shows what has
changed.
