Can I remove this code from wp-cache-base.php ??

This is what I on turning debug on in wordpress.

Fatal error: Internal Zend error – Missing class information for in /mysite/folders/wp-cache-base.php on line 4

If I remove this code

if (!class_exists('CacheMeta')) {
	class CacheMeta {
		var $dynamic = false;
		var $headers = array();
		var $uri = '';
		var $post = 0;
	}
}

the error is gone. So my question is, is that code really important, what does it serve? Can removing it be dangerous?
