Actually, APR does promise that "." and ".." will be returned, and
will be returned first, on all platforms.

See apr/include/apr_file_info.h:

    * Read the next entry from the specified directory.
    * @param finfo the file info structure and filled in by apr_dir_read
    * @param wanted The desired apr_finfo_t fields, as a bit flag of \
      APR_FINFO_ values
    * @param thedir the directory descriptor returned from apr_dir_open
    * @remark All systems return . and .. as the first two files.
   APR_DECLARE(apr_status_t) apr_dir_read(apr_finfo_t *finfo,

Agreed, can make up a better status code for this.

I don't know. Anyone know?
