In this case I agree with Evan, and I see the argv loop idiomatic.
I have seen in several books and in diferent sources. I usually
do the argv loop:

        for (++argv; *argv; ++argc)

                or

        while (*++argv)

and if I need do a test argc > something then I update the value of argc
in the body. If I only need argc > 0 I use *argv != 0.
