The problem is, one way or another, related to the noncopyable idiom (deriving from a class with private copy ctr and assignment operator.) Maybe the following, more convoluted snippet will MSVC 7.1 emit the warning:
#include <boost/noncopyable.hpp>
class bar:boost::noncopyable { };
template<typename T> class foo:bar { public: foo(int x=0); };
foo<int> f;
Well, it does now. Thanks for this. I will suggest a patch for these warnings into boost MSVC compiler config so that all libraries can benefit from this. But what about boost\multi_index\detail\hash_index_node.hpp(89) : warning C4610: struct 'boost::multi_index::detail::hashed_index_node_trampoline<Super>' can never be instantiated - user defined constructor required This warning seems to have more sense and should not be disabled perhaps. Do you think it should be disabled on whole Boost level as well?
