--- Comment #2 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
For the simplest case (A && A), we warn with -Wlogical-op:

int foo(int a, int b, int c)
{
    if(b == c && b == c) return 1; /* warn */
    if(a && b == c && b == c) return 2; /* missing warning */
    return 0;
}

Also PR71345.
