Since adjacency_list.hpp includes ct_if.hpp too, and makes use of it, I'm
pretty sure it is broken in the same way -- which means all the BGL is

Maybe, it's the right time to switch from ct_if.hpp to MPL? The attached patch
does that and fixes all tests. Or course, the change may be considered to
large before release. Opinions?

Agh.. and deprecation of compose-* has independently broken
transvitive_closure -- which I gonna fix.

And besides, would anyone mind if I add BGL to regression tests?
