When building kdepim-runtime there are several warnings reported by the compiler, e.g.

warning: unused parameter ‘parentWidget’ [-Wunused-parameter]

or

warning: 'MessageThreadingAttribute' is deprecated [-Wdeprecated-declarations]

This task is about fixing 31 of any warning reported by the compiler.

Some, like the deprecation warning are not easy to fix without deep understanding of the code and should be skipped.

The deliverable is a review request containing all 31 fixed on git.reviewboard.kde.org
