  TODO:  Right now, only the SCons generator supports this, so the
  test case is SCons-specific.  In particular, it relise on SCons'
  ability to rebuild in response to changes on the command line.  It
  may be simpler to just drop this feature if the other generators
  can't be made to behave the same way.
