Don’t dump core if argv[0] is NULL, which is allowed on
GNU/Linux if the invoker is sufficiently perverse.
* zdump.c (progname): Now char const *, so that it can be given
the address of a string constant.
(tzalloc): Use optarg, not progname, since progname’s type is no
longer correct.
* zdump.c, zic.c (main): Initialize progname to non-null.

Subject: [PATCH] Fix unlikely conversion bug in zic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* zic.c (puttzcode): Arg is zic_t, not int_fast32_t.  This fixes a
portability bug on platforms where int_fast32_t is a 32-bit ones’
complement or signed-magnitude integer, and where the argument is
-2**31 before conversion to int_fast32_t.  Although I don’t know
of any such platforms, the C standard allows them.
