Install tool cannot compare "ENGINE" of MySQL Tables when DBAL is active
In core rev. 3365 (2008, was included in 4.2beta3), Stucki implemented a way of the Install Tool "COMPARE DATABASE" to change the Engine of a database. This does not work with DBAL enabled, because that change in t3lib_db was not ported to DBAL.
You end up with the same suggestions over and over again (to change Engine to "InnoDB" while the tables are already InnoDB).
