Another way (How not to write a loop)

[Ray Butterworth]

I just got hit by yet another way not to write a loop:

    auto size_t index;

    index = sizeof(array) / sizeof(array[0]);

    while (--index >= 0)
        blah blah blah

This looks wonderfully portable and works fine on the BSD 4.3 compiler
(and probably most others).

But on an ANSI compiler, (size_t) will be an unsigned integer
and the loop will go forever.

Lint will notice this problem, but only with the ANSI compiler
when it is probably too late.
