Mea culpa.  First I go off and complain about partially or completely
incorrect answers to his simple question, and then, as has been pointed
out to my in e-mail by <ico.isc.com!rcd> that my solution also contains
an error:

	char *duh = "Hello";

duh points to a constant string.  Should've been

	char duh[] = "Hello";

Now, maybe I just didn't want to start a whole go-around again about
the difference between the two, or maybe I was too lazy to explain,
or maybe (and this is the most likely) I just overlooked it. 

Oooopppps!    <sheepish :) :)>
