Jigsaw 2.x.x and PHP4

Hello there,

Is there a full compatibility between Jigsaw 2.0.5 and PHP4 ?
My problem is that each time I try to execute a php scipt on my server, I have the following security alert in my php.ini , although I have set the cgi.redirect_status_env and cgi.redisect_status to 1 :

-> output beginning
Security Alert! The PHP CGI cannot be accessed directly. 
This PHP CGI binary was compiled with force-cgi-redirect enabled. This means that a page will only be served up if the REDIRECT_STATUS CGI variable is set, e.g. via an Apache Action directive.

For more information as to why this behaviour exists, see the manual page for CGI security.

For more information about changing this behaviour or re-enabling this webserver, consult the installation file that came with this distribution, or visit the manual page.

-> output end

Maybe it is a compatibility issue ? Does this problem already occur to someone ?

NB : my php version is 4.2.1

Thanks for your answers !
