call time pass by reference - help

There are a number of methods in the session class of phplib. With phplib and php4.0.4 I am seeing the following warnings: Warning: Call-time pass-by-reference has been deprecated - argument passed by value; 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. However, future versions may not support this any longer. in /adm/vhosts/theparentreport.com/www/phplib/session.inc on line 273 Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of [runtime function name]().
