PHP Fatal error: Cannot redeclare wp_cache_add() #341

Hi,

The drop-in is throwing a fatal error;

PHP Fatal error: Cannot redeclare wp_cache_add()
(previously declared in /<path>/public/wp-content/object-cache.php:33) in /<path>/public/wp-includes/cache.php on line 30"

The wp_cache_add() function is not mentioned in the pluggable functions. Nevertheless, several Redis plugins override this function (and it's siblings) inside a drop-in.

All help is appreciated!
