Ah, yes. The proposed patch does not have this problem but you're
generally right. In fact, I have this wonderful piece of code in some of my
projects' configure.ac (I also took it from somewhere but can't remember
where):

for i in prefix localstatedir sysconfdir; do
        name=`echo $i | sed -e 's/dir$//' | $TR 'a-z' 'A-Z'`
        x="\$$i"
        eval y="$x"
        while test "$x" != "$y"; do
                x="$y"
                eval y="$x"
        done
        AC_DEFINE_UNQUOTED([DIR_$name], ["$x"])
done
