The general approach should be to leave the forwarding stub with 
BOOST_HEADER_DEPRECATED in it for a release or two, allowing existing users 
to migrate, then remove; but for this to work there needs to be an 
alternative to which people can migrate. Do we have an equivalent of 
lowest_bit in Boost.Integer? Is it just log2?
