Commit Message
Here's an alternative for the test-case, trivially
generating the binary tzfile from a source. At first I
though re-sending just the first version but split up as the
first alternative, but on second thought that would just be
undesired and confusing.
Generating the file using the specific zic version *for the
purpose of covering the fixed bug* would add a dependency to
install exactly 2021d or 2021e only to be used by this test,
and I don't think that's appropriate. Better use a
shell-script and printf as suggested. Hopefully digestible
for both maintainers and CI tools.
Happy Holidays in advance.

This test-case is the tzfile for Asuncion generated by
tzlib-2021e as follows, using the tzlib-2021e zic: "zic -d
DEST -r @1546300800 -L /dev/null -b slim
SOURCE/southamerica". Note that in its type 2 header, it
has two entries in its "time-types" array (types), but only
one entry in its "transition types" array (type_idxs).
* timezone/Makefile, timezone/tst-pr28707.c,
timezone/testdata/gen-XT5.sh: New test.

Oops, sorry about that line. Mishap from internal
git-hooks... Please delete this when applying!
(Or do I need to send a new version?)
