The mask used in the assignment or the value used in the comparison may come from a macro expansion, and be compile-time dependent. Or the comparison may be some kind of debug/assert check to ensure people don't mess up the assignment. Does cppcheck document what is actually warned and what is not and how to work-around the warning in case the code is actually valid? I am sure cppcheck warns about a lot of things that GCC does not, but the difficulty lies in getting the corner-cases right and the right level of warning versus annoying users.
