The coding guideline rule C-TY-12 requires that 'all type conversions shall be explicit'. Especially implicit cases on the signedness of variables shall be avoided. This patch either adds explicit type casts or adjust local variable types to make sure that Booleans, signed and unsigned integers are not used mixedly. This patch has no semantic changes.
