      ぢょ〜@よくきたなです．
      PHP 4.1.2，4.2.3，4.3.7，4.4.2 も同様に見えます．下記 4.3.7
    のソースから引用．

PHP_FUNCTION(mb_strpos)

        pval **arg1, **arg2, **arg3, **arg4;
        int offset, n, reverse = 0;

        needle.no_encoding = MBSTRG(current_internal_encoding);
        offset = 0;
        switch (ZEND_NUM_ARGS()) {
        case 2:
                if (zend_get_parameters_ex(2, &arg1, &arg2) == FAILURE) {
                        WRONG_PARAM_COUNT;
                }
                break;
        case 3:
                if (zend_get_parameters_ex(3, &arg1, &arg2, &arg3) == FAILURE) {

                        php_error_docref(NULL TSRMLS_CC, E_WARNING, "Unknown encoding \"%s\"", Z_STRVAL_PP(arg4));
                        RETURN_FALSE;
                }
                break;
        default:
