I have to say that I am not happy that we so fast resort to reintroducing
such hooks, when the goal of the initial patch from you was that we
should not have to meddle with the include directive to begin with...

I would favour trying to fix it in a cleaner way, either my previous
patchset (or something similar) to conditionally add the correct list
of directories, or to mege back autoconf-archive back into the main
include directory and see what package break and fix those instead.

However, we currently have a single package that depends on
autoconf-archive, so I would not put too much effort in it either...

Thomas, Arnout, Peter: thoghts?
