Explicit instantiation failing in 3.5 (boost)

[Lars Gullik Bjønnes]

This is adapted from code in connection.hpp in boost.

Should it work or is the code in fact wrong, and makes assumptions
that the standard does not provide?

------
#include <list>

struct bound_object {
        bool operator==(const bound_object& other) const;
        bool operator<(const bound_object& other) const;
};

template class std::list<bound_object>;
