We don't test every module with every configuration. It's just too many 
permutations possible.

Thanks for reporting, those issues are easy to fix. The line in question is:

            bottomRight.setLatitude(qMax(bottomRight.latitude(),
                                                 -85.05113));

To fix this, the literal number needs to be written as: qreal(-85.05113). 
There's also a qMin line right above with the same problem.
