The nice version error message doesn't work if php version is < 5.0.
The user se instead:

Parse error: syntax error, unexpected ',', expecting '(' in /srv/web/dan/ezp4.example.com/httpdocs/index.php on line 122

Here is a simple workaround. May be there are cleaner way to achieve
this. Others files could require this, for example webdaw.php.
