php 5.3

Hi,
Since updating php to version 5.3.3 my phpwiki is failing with errors 
such as this:
lib/FileFinder.php:159 Error[8192]: Function ereg() is deprecated
>From looking around on the web I see that it is possible to work 
around this by putting in -E_DEPRECATED somewhere, but I can't see 
where.
Is it possible someone could provide a quick patch to put in 
-E_DEPRECATED and get me running again.
I appreciate there may be other reasons it won't work with 5.3.3 and a 
longer term solution will be required, but if it's only a case of 
switching off the deprecated function errors then I'd rather go with 
that than downgrade php.
Thanks
Peter
