-Wall not detecting uninitialized variables

[sudhakar govindavajhala <sudhakarg79spam@xxxxxxxxx>]

Hello all,

How come -Wall is not detecting unitialized variables?

Thanks,
Sudhakar

$cat test.c
#include <stdio.h>

int main() {
        int i;
        printf(" hi sud %d \n", i);
        return 0;

}
