Rather a bit of overkill to write a C program for it isn't it?
The script below, hacked out in about 30 seconds, does most of what
want-- adding an -if- to check for the trailing .Z files is left
as an exercise for the reader :-).  You can also add a check for
a $1 that was already all lower case if you want.

#!/bin/ksh
while [ -n "$1" ]
do
    typeset -l LC="$1"
    mv "$1" "${LC}"
    shift
done

I suppose I should offer a (slower) Bourne shell version for
anyone unlucky enough to still be limited to that:  I'm
sure someone can probably improve on this and make it even
shorter. (You can probably write it in perl in 1 line.)

#!/bin/sh
while [ "$1" != "" ]
do
    mv $1 `echo $1 | tr "[A-Z]" "[a-z]"`
    shift
done
