This lets zic handle the time rules of Troll station,
Antarctica. Adapted from a fix by Zefram in:
http://mm.icann.org/pipermail/tz/2014-March/020759.html
* zic.c (timecnt_alloc): New static var.
(attypes): Now a pointer to an array, not a fixed size array.
(writezone, addtt): Don't assume the number of times is less than
TZ_MAX_TIMES.
* NEWS: Document this.
* europe (Europe/Simferopol), NEWS:
Crimea switches to MSK on 2014-03-30 at 02:00 local time.
(Thanks to Alexander Krivenyshev.)
* zone.tab: Move its zone.tab entry from UA to RU.
* tz-link.htm, NEWS: Fix misstatement about which part of the
Microsoft Windows software universe supports tz database names.
(Thanks to Donald MacQueen.)
* tz-link.htm, NEWS: Add Time.is (thanks to Even Scharning), WX-now
(thanks to David Braverman), TZ4Net (thanks to Matt Johnson).
Remove Simple Timer + Clocks.
* tz-link.htm: Mention zeitverschiebung.net (thanks to Martin
Jaeger) and the timezone-olson Haskell package. Remove moribund
link to daylight-savings-time.info.
* NEWS: Document this.
* tz-link.htm: Mention xCal and jCal.
Mention Microsoft Windows 8.1 support for tz names.
CLDR data is available in both XML and JSON form.
Update two links (thanks to Oscar van Vlijmen).
Fix some formatting glitches, e.g., remove random newlines from
abbr elements' title attributes.
* NEWS: Document this.
* localtime.c (tzload) [ALL_STATE]: Initialize sp->goback
and sp->goahead even if memory allocation fails.
(tzload, tzsetwall, tzset, gmtsub) [ALL_STATE]:
Use malloc, not calloc, since the !ALL_STATE code has to
work with reused storage anyway.
* NEWS: Document Logan Chien's fix.
* asia (Jordan, Asia/Amman): Jordan switches back to standard time
on 2013-12-20. (Thanks to Steffen Thorsen.) Assume this is at
00:00s, and that the previous schedule resumes next year.
* NEWS: Document this.
The current tzdata now goes to 17, which is uncomfortably close to
the NOSOLAR limit of 20.
* Makefile (CFLAGS): Remove NOSOLAR comment.
* tzfile.h (TZ_MAX_TYPES): Ignore NOSOLAR; always default to 256.
* NEWS: Document this.
(Thanks to Even Scharning for the heads-up.)
* africa (Libya): DST rules are for 2013 only.
(Africa/Tripoli): Switch to EET without DST as of 02:00 today.
* NEWS: Document this.
Problem reported by Patrick 'P. J.' McDermott in
<http://mm.icann.org/pipermail/tz/2013-October/020441.html>.
This code is quite a bit different from what he proposed.
* tzselect.ksh: Rewrite so that it should work with /bin/sh on
common platforms. For portability to Solaris 9 /bin/sh, use
`...`, not $(...), and avoid $((...)).
(doselect): New function. Use this instead of plain 'select'.
Callers no longer need to worry whether it sets the var to empty.
* Makefile, NEWS: Document this.
* zic.c (outzone): Restore diagnostic that was inadvertently
suppressed by the 2013-09-08 change to the 400-years-hack.
This doesn't affect zic's binary output; it affects only the
diagnostics generated by 'zic -v'. The problem evinced itself
with Asia/Tehran, which currently should generate a diagnostic,
but doesn't without this patch.
* NEWS: Document the above.
MinGW problem reported by Theo Veenker in
<http://mm.icann.org/pipermail/tz/2013-September/020378.html>.
The patched code should work even on POSIXish hosts
where 'link' and 'symlink' fail for whatever reason,
e.g., if the destination file system is VFAT.
Also, the patch fixes some bugs when symlinks are used.
* Makefile (CFLAGS): Mention HAVE_LINK in the comment.
(TZDSRCS): Add asctime.o, since MinGW lacks asctime.
(TZDOBJS): Add asctime.c.
* private.h (HAVE_LINK): Default to 1.
* zic.c (link) [!HAVE_LINK]: New macro.
(symlink) [!HAVE_SYMLINK]: New macro.
(dolink): Fix some bugs when 'link' fails but 'symlink' succeeds.
Fall back on copying when both fail.
* NEWS: Document the above.
