{
  (void) path_size;

  return (jerry_char_t *) realpath ((char *) path_p, NULL);
} /* jerry_port_path_normalize */
```
Currently the implementation of jerry_port_path_normalize  are called realpath directly, than
may return NULL when path_p is not NULL, but that's not expected.


on unix, realpath are can failed when the path not exist
