[PATCH] small bug? in parse_{for,while}_statement

[Oleg Nesterov]

Without this patch evaluate_iterator() evaluates
stmt->iterator_pre_condition twice.

Code:
        static void f(void)
        {
                for ( ; x; );
        }

output:

        tst.c:3:10: warning: undefined identifier 'x'
        tst.c:3:10: warning: undefined identifier 'x'
