Well, it is not enabled (right) in 4.2 so the fix should stay in 4.2.
For 4.3 we should rethink this. I have had only a quick glance at the
code but I wasn't sure what exactlyx you tried to achieve. If no
collation is given then Mysql will choose it's default collation. So why
bother trying to get the settings for the server (which is probably a
built-in unchangeable valuue anyway).

Furthermore we DID NOT require a sepcifi Mysql version so TYPO3 MUST run
without error. I'm unhappy that a half-baked feature that crept makes
now so many troubles.
