Yep, if you include the same file more than once recursively then 
the '__FILE__.pre-$(1)'-based approach won't be able to restore 
previous path.

I've been using basically the same technique (plus fix for the problem 
mentioned above) for a while now. It works pretty well. Also with this
approach you get the ability to create makefile-local variables.

I you are interested I can email you my implementation.
