Broken (again?) in 4.1

$ cat u.c
typedef unsigned long u64;

struct pal_freq_ratio {
        u64 den : 32, num : 32; /* numerator & denominator */
} x;

main()
{
        printf("den=%lx num=%lx\n", x.den, x.num);
}
$ cc -Wformat u.c
u.c:9: warning: format ‘%lx’ expects type ‘long unsigned int’, but argument 2
