Thanks Jeremy, I've updated from the CVS, though this seems to have
introduced more problems:

I tried to get to the bottom of this myself, but I've been finding it
difficult to make heads nor tails of what's going on here ;) I got as far as
#include-ing "pending/ct-if.hpp" in named_template_params.hpp, but that
didn't solve much...
