...checking for unnecessary uses of more "fake bool" types. In the past, some of the checks involving the types of variables or data members, or the return types of functions, issued warnings that required surrounding code to be changed too (e.g., when changing the signature of a function whose address was taken). These checks have been tightened now to not warn in such cases (which avoids warnings that require changes to additional code, or changes that might even be impossible to make, at the cost of being less aggressive about removing all unnecessary uses of those "fake bool" types).
