Comment 15 for bug 291780

I'm not sure this is fixed, please correct me if wrong, but

    #include <stdio.h>
    #include <stdint.h>

    int main(void)
    {
        const uint8_t u = 0U;
        const uint8_t y = (uint8_t) ~u;

        return ((uint8_t) u != (uint8_t) ~y);
    }

gives warning

    test.c: In function ‘main’:
    test.c:9:25: warning: comparison of promoted bitwise complement of an unsigned value with unsigned [-Wsign-compare]
        9 | return ((uint8_t) u != (uint8_t) ~y);
          | ^~

Does this not mean that this issue is still present?
