[boost] noexcept(true) for ~noncopyable?

Shouldn't ~noncopyable be noexcept? I'm seeing this error: class Cconnection : public Cclient, boost::noncopyable connection.h:5:7: error: looser throw specifier for ‘virtual Cconnection::~Cconnection()’ In file included from connection.h:3:0, from connection.cpp:2: client.h:10:10: error: overriding ‘virtual Cclient::~Cclient() noexcept (true)’ https://svn.boost.org/trac/boost/ticket/10698 -- Olaf
