  Commit 1f94147a79fcb7211f1421b87383cad93986797f ("timezone: sync to
TZDB 2024a") changed the default output format to -b slim, which
causes problems for some current software versions (notably pytz).

+* The bundled timezone data compiler, zic, now defaults to the “slim”
+  output format.  This format does not include 32-bit time zone data in
+  the generated TZif files.  If the system time zone database is
+  compiled with the default zic settings, applications that read the
+  timezone database directly and do not process the 64-bit part of the
