2.6 FP on static variable?

[jacob s]

int get_delta() {
    clock_t now_ms = (clock() / (CLOCKS_PER_SEC / 1000));
    static clock_t last_clock_ms = now_ms;
    clock_t delta = now_ms - last_clock_ms;
    last_clock_ms = now_ms;

    if (delta > 50)
        delta = 50;
    return delta;
}

gives

fp.c:7:15: style: Condition 'delta>50' is always false [knownConditionTrueFalse]
    if (delta > 50)
              ^
fp.c:3:34: note: last_clock_ms is assigned 'now_ms' here.
    static clock_t last_clock_ms = now_ms;
                                 ^
fp.c:4:28: note: Assignment 'delta=now_ms-last_clock_ms', assigned value is 0
    clock_t delta = now_ms - last_clock_ms;
                           ^
fp.c:7:15: note: Condition 'delta>50' is always false
    if (delta > 50)

which is only true for the first call. this warning was not thrown with 2.5.
