I'm not following you. If you use -Ishadow-tree/include, and the
shadow-tree has every include from evere package that's in the base
tree, what has that bought you?

I understand that. My question is, why are you build-linking "imake"
packages, which _don't_ share GNU configure's philosophy.

Why don't you tell us exactly what problem you're trying to fix (which
packages), so we can see if there's a better way of fixing the problem
than imposing a shadow tree under ${LOCALBASE}?
