/* With the traditional VPATH setting, it is not possible to
   simultaneously compile in-place and in another directory.  The
   mistaken definition is that *all* dependencies are searched for in
   the VPATH directory, rather than just the dependencies that are not
   themselves targets.  Thus, if there is an up-to-date .o file in the
   in-place location, it will not get recompiled in the not-in-place
   location.

   The GNU Make "vpath" directive continues this tradition, but at
   least lets you restrict the classes of files that it applies to.
   This allows us to kludge around the problem. */
