        * acinclude.m4 (GLIBCXX_CHECK_FILESYSTEM_DEPS): Check _XOPEN_VERSION
        and PATH_MAX for _GLIBCXX_USE_REALPATH.  Remove _GLIBCXX_ prefix
        from HAVE_STRUCT_DIRENT_D_TYPE.

        (_Dir::advance): Use readdir instead of native_readdir.
        (recursive_directory_iterator(const path&, directory_options,
        error_code*)): Use swap instead of reset.
        (ErrorCode): Remove.
        (_Dir::advance): Change ErrorCode parameter to error_code*, add
        directory_options parameter and check it on error.
        (opendir): Rename to open_dir to avoid clashing with macro. Change
        ErrorCode parameter to error_code*.
        (make_shared_dir): Remove.

        (directory_iterator(const path&, directory_options, error_code*)):
        Pass options to _Dir::advance and create non-end iterator on error.
        (recursive_directory_iterator(const path&, directory_options,
        error_code*)): Clear error_code on ignored error, create non-end
        iterator otherwise.

        _Dir::advance.
