Missed int promotion with indirect bit-field expressions

[fuhsnn]

#include <stdio.h>

int main(void) {
    struct { unsigned b : 3; } s = {0};
    printf("%d\n", (~(0,s.b) < 0) ); // expected 1
    printf("%d\n", (~({s.b;}) < 0) ); // expected 1
    printf("%d\n", (~(1 ? s.b : s.b) < 0) ); // expected 1
}
