The current WP still contains a concept_map.

[ 2009-11-11 Moved to Tentatively Ready after 5 positive votes on c++std-lib. ]

Proposed resolution:

Change Iostreams base classes 31.5 [iostreams.base], Header <ios> synopsis, as indicated:

concept_map ErrorCodeEnum<io_errc> { };
template <> struct is_error_code_enum<io_errc> : true_type { }
error_code make_error_code(io_errc e);
error_condition make_error_condition(io_errc e);
const error_category& iostream_category();
