## 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.
