    Code:
    while (n < MAX) {
           divisible = FALSE;
           for (i = 0; (i < sqrt(n)) && !divisible; i++)
               divisible = ((candidat % p[i]) == 0);
    Is it that ?

    I think like that its more slow!

    Well try not calling sqrt() so many times - like just ONCE before the loop, not every time within the loop.

    Bored now.....


    int limit = sqrt ( fooo );
    for (i = 0; i < limit ; i++ )

    If you can't get that into your code, give it up
