[Bug c/45493] New: -Wuninitialized does not warn

[tadhunt at gmail dot com]

When the first use of an uninitialized variable is inside a loop, no warning is
generated when -Wuninitialized is turned on.

int
main(void)
{
        int len, i;

        for(i = 0; i < 5; i++) {
                printf("%d\n", len);            // no warning!
                len = 10;
        }

        return 0;
}
