The `struct diff_flags` structure is essentially an array of flags, all of which have the same type. We can thus use `sizeof()` to iterate through all of the flags, which we do in `diff_flags_or()`. But while the statement returns an unsigned integer, we used a signed integer to iterate through the flags, which generates a warning. Fix this by using `size_t` for the index instead.
