On trying to install by calling http://.../w/config/index.php MediaWiki 1.18alpha (r79596)
Bug is still present in absolutely current SVN checkout 1.18alpha (r80710)
install_version_checks() doesn't exist in trunk, so that's not possible. I'm willing to bet you have a mix of old and new files. config/index.php certainly does not call this old function.
Apologies, I confirm, the config files remained in the wrong version. Thanks for the help!
