    CI: Avoid cppcheck false positives
    
    Various changes to avoid false positives in cppcheck.
    
    The 'alternative int' specifier isn't known to cppcheck so always run the
    checks as if it is not defined.
    
    Cppcheck has trouble deducing the type of one 'auto' variable, so just
    replace it with its real type.
