Wow, then GCC must be REALLY REALLY broken!  Observe:

int a(int x)
{
    printf("evaluating a\n");
    return x;
}

int b(int x)
{
    printf("evaluating b\n");
    return x;
}

int c(int x)
{
    printf("evaluating c\n");
    return x;
}

int main()
{
    printf("a(0) && b(5) || c(5)    result: %d\n", a(0) && b(5) || c(5));
    printf("a(1) && b(5) || c(5)    result: %d\n", a(1) && b(5) || c(5));
}

-------[ output ]------
evaluating a
evaluating c
a(0) && b(5) || c(5)    result: 1
evaluating a
evaluating b
a(1) && b(5) || c(5)    result: 1

You can say that again!
