At least gcc doesn't do the suggestion in that particular case:


foo.c: In function 'foo':
foo.c:8:7: error: 'j' undeclared (first use in this function)
        8 | x[j] = a[i] > b[i];
            | ^
foo.c:8:7: note: each undeclared identifier is reported only once for each function it appears in
