* In glibc nl_catd type is void *, but messages_base::catalog is defined as int
* by ISO/IEC 14882; The int may be too short to store pointer on 64-bit platforms;
* Another problem, is that do_open() may return negative value to indicate that no
* catalog open---this case can't be represented with pointers.
* The class _Catalog_nl_catd_map intended to make relation between
* messages_base::catalog and nl_catd handler.
/* If no mapping a message_base::catalog entry, int typedef according C++ Standard,
* has to be large enough to contain a nl_catd_type value.
