std::num_put<char, char*>

Essentially right, this is Table 52.

                                                               but it appears the libstdc++

On purpose. Table 51 only mandates that has_facet<num_put<char> >(loc) shall be true, for any loc either constructed or returned by locale::classic(). Nothing is said about, legal, additional, facets identified by a given locale. In principle, that is an unbounded set, one for each possible output iterator type...
