"make check" certainly *will* run zic.c, while creating the temporary
installation.  (Unless you use --with-system-tzdata, which I'm sure
most production builds do.)  But our test suite touches only a very
tiny fraction of the tzdata files, so even if there's some
corruption in them we wouldn't necessarily notice it.
