Wine has all that fonts except serife.fon. It's not clear to me what CCleaner is complaining about.
Sorry, forgot the actual error message: "The Font coure.fon could not be found. These references are often left behind after uninstalling software.
Solution: Delete the registry value."
Apparently it's looking for the file to actually exist. A simple 'touch $HOME/.wine/drive_c/windows/Fonts/{serife,sserife,coure,smalle}.fon' is enough to make it happy...
