The idea is to have NO changes required.

The rub is that Configure "assumes" that modules are setup as


and only that deep. For 2.0 it would be nice to have


and similar things. We could even make it generic enough so that
AddModule could be use to add regex or expat or anything else.
This sort of internal monkeying around may not be suited for
autoconf... I have no idea how autoconf can do the kind of Module
manipulation (including the run-time stuff) we're currently doing.
