I'm not going to take the time to read through your code.  I have enough
buggy code of my own to look at. -:)  I will give you one major hint.
What qsort passes to the sort function has ONE MORE LEVEL OF INDIRECTION
than you might expect.  For example, if you are trying to sort

char	*barf[MAXBARF];

the qsort call is

qsort( (char *) barf, MAXBARF, sizeof(char **), sortfunc)

and

sortfunc(as,bs)
char	**as;
char	**bs;
{
	return(strcmp(*as,*bs));
}

Happy sorting.
