The only thing I've got is the shell script below (known as "zgress"
locally).

				--ado

#!/bin/sh

# Accept the names of two time zone package source directories (A and
B).
# Do a "make install" from each directory to temporary directories.
# Apply the created "zdump" programs to all the created binary data
files:
#	the A zdump to the A data (yielding AA results)
#	the A zdump to the B data (yielding AB results)
#	the B zdump to the A data (yielding BA results)
#	the B zdump to the B data (yielding BB results)
# Report on differences.

O=`basename "$0"`

case $# in
	2)	;;
	*)	echo "$O: usage is $O atzsourcedir btzsourcedir" 1>&2
		exit 1

trap 'rm -f -r $T*' 0 1 2 3 15

# Step 1: do "make"s for both the A and B versions

for pass in a b
do
	( cd "$1"; make clean; make install TOPDIR=$T$pass ) || exit 1
	shift
done

# Step 2: apply both the A and B zdumps to both the A and B data

for prog in a b
do
	for data in a b
	do
		zdump=$T$prog/etc/zdump
		zoneinfo=$T$data/etc/zoneinfo
		$zdump -v `find $zoneinfo ! -type d -print | sort` 2>&-
|
			sed "s@$zoneinfo/@@" > $T$prog$data
	done
done

# Step 3: do comparisons

ls -l $T[ab][ab]

left=aa

for right in ab ba bb
do
	diff $T$left $T$right | sed "s/^/$left vs. $right:/"
done
