I've reverted SpecialWhatlinkshere.php to the pre-r35371 state so it works again on Wikimedia.
I don't see any subqueries that this runs, only unions. I think that comment is using "subquery" loosely to mean "one of the queries in a union". The docs say that UNION is available beginning in MySQL 4.0.0. What query gave an error?
