Under SVR4:

    /home/campbell> cat test.c
    #include <stdio.h>
    
    void foo(int a, int b)
    {
        if (a = b)
            (void) printf("yow!\n");
    }
    /home/campbell> lint -u test.c
    (5) warning: assignment operator "=" found where "==" was expected
    
    set but not used in function
        (3) a in foo

I think the lint that comes with it is itself reason enough to run SVR4.
