[Xitami] Newbie question: Xitami and php

[Ed op Het Net]

I have Xitami up and running on Windows 98 SE.
I've installed the latest distribution of php4.
Now, whenever I open a php-file (like phpinfo.php)
in my browser on the localhost-adress I receive the following message:

"Security Alert! 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. This variable is set, for example, by Apache's Action directive redirect. 
You may disable this restriction by recompiling the PHP binary with
the --disable-force-cgi-redirect switch. If you do this and you have your
PHP CGI binary accessible somewhere in your web tree, people will be able to
circumvent .htaccess security by loading files through the PHP parser.
A good way around this is to define doc_root in your php.ini file to something other
than your top-level DOCUMENT_ROOT. This way you can separate the part of your web space
which uses PHP from the normal part using .htaccess security. If you do not have
any .htaccess restrictions anywhere on your site you can leave doc_root undefined.
If you are running IIS, you may safely set cgi.force_redirect=0 in
php.ini."

I tried everything, but I can't get it to work, and an internet- and
faq-search didn't make me any wiser.
Can someone explain me in plain and simple English which steps I have
to take to solve this?

Thanks in advance, Edward
