John Maddock's fix to is_base_and_derived to make it complain about the use of incomplete types (see http://svn.boost.org/trac/boost/ changeset/39219) broke something within the parameter library.

I've committed the following patch to the parameter library, which fixes the problem. Unless there was a particular reason not to include the "maybe" header from arg_list.hpp?

Looks good to me; thanks for the fix! -- Dave Abrahams Boost Consulting http://www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
