 I'm confused by the error message you received because `ZEND_RESULT_CODE
 *` is not the return type on that line of that file; `int` is.
 `ZEND_RESULT_CODE` doesn't seem to appear anywhere within the rar module's
 code.

 When I build the port with MacPorts clang 19 on macOS 12 the error I get
 is:

 {{{
 /path/to/rar-4.2.0/rararch.c:1244:42: error: incompatible function pointer
 types assigning to 'zend_object_count_elements_t' (aka 'ZEND_RESULT_CODE
 (*)(struct _zend_object *, long long *)') from 'int (handler_this_t *,
 long *)' (aka 'int (struct _zend_object *, long *)') [-Wincompatible-
 function-pointer-types]
  1244 |         rararch_object_handlers.count_elements  =
 rararch_count_elements;
       |                                                 ^
 ~~~~~~~~~~~~~~~~~~~~~~
 }}}

 Could it be that you experienced that error, then tried to fix it by
 changing the return type from `int` to `ZEND_RESULT_CODE *`, then
 encountered the `conflicting types for 'rararch_count_elements'` error and
 reported it?
