When i change PHP 4.4.7 to PHP 5.2, i recieve following warning on every page:

Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. in D:\work\sites\drupal\sites\all\modules\typografica\typografica.module on line 104
