Details:
I am using 'Advanced Auto-Dependency Generation' described at
http://make.paulandlesley.org/autodep.html together with VPATH.
When source file is moved from one location in VPATH into another one (usual
situation in our project), make still try to use a source file in old
location.
I created a script (attached) to illustrate a problem.
