 * Parameters: fname      - [IN] filename to be checked                       *

 *             regex_incl - [IN] regexp for filenames to include (NULL means  *

 * Return value: If filename passes both checks, nonzero value is returned.   *

 *               If filename fails to pass, 0 is returned.                    *
