GCC can still be really stupid and issue warnings about code that's
perfectly fine, for example:

[rmccabe at sublimit ~]$ cat test.c
int main(void) {
    int x, y = 1;
    if (y || x)
        x = 1;
    return 0;
}

[rmccabe at sublimit ~]$ gcc -O2 -Wall -Werror test.c -o test
cc1: warnings being treated as errors
test.c: In function ?main?:
test.c:3: warning: ?x? is used uninitialized in this function
