Log Message:
Merge tzcode2018c [ changelog with changes to tzdata sections removed ]

Release 2018c - 2018-01-22 23:00:44 -0800

  Changes to build procedure

    The build procedure now works around mawk 1.3.3's lack of support
    for character class expressions.  (Problem reported by Ohyama.)

Release 2018b - 2018-01-17 23:24:48 -0800

  Changes to build procedure

    The distribution now contains the file 'pacificnew' again.
    This file was inadvertantly omitted in the 2018a distribution.
    (Problem reported by Matias Fonzo.)

Release 2018a - 2018-01-12 22:29:21 -0800

  Changes to build procedure

    The default installation locations have been changed to mostly
    match Debian circa 2017, instead of being designed as an add-on to
    4.3BSD circa 1986.  This affects the Makefile macros TOPDIR,
    TZDIR, MANDIR, and LIBDIR.  New Makefile macros TZDEFAULT, USRDIR,
    USRSHAREDIR, BINDIR, ZDUMPDIR, and ZICDIR let installers tailor
    locations more precisely.  (This responds to suggestions from
    Brian Inglis and from Steve Summit.)

    The default installation procedure no longer creates the
    backward-compatibility link US/Pacific-New, which causes
    confusion during user setup (e.g., see Debian bug 815200).
    Use 'make BACKWARD="backward pacificnew"' to create the link
    anyway, for now.  Eventually we plan to remove the link entirely.

    tzdata.zi now contains a version-number comment.
    (Suggested by Tom Lane.)

    The Makefile now quotes values like BACKWARD more carefully when
    passing them to the shell.  (Problem reported by Zefram.)

    Builders no longer need to specify -DHAVE_SNPRINTF on platforms
    that have snprintf and use pre-C99 compilers.  (Problem reported
    by Jon Skeet.)

  Changes to code

    zic has a new option -t FILE that specifies the location of the
    file that determines local time when TZ is unset.  The default for
    this location can be configured via the new TZDEFAULT makefile
    macro, which defaults to /etc/localtime.

    Diagnostics and commentary now distinguish UT from UTC more
    carefully; see theory.html for more information about UT vs UTC.

    zic has been ported to GCC 8's -Wstringop-truncation option.
    (Problem reported by Martin Sebor.)

  Changes to documentation and commentary

    The zic man page now documents the longstanding behavior that
    times and years can be out of the usual range, with negative times
    counting backwards from midnight and with year 0 preceding year 1.
    (Problem reported by Michael Deckers.)

    The theory.html file now mentions the POSIX limit of six chars
    per abbreviation, and lists alphabetic abbreviations used.

    The files tz-art.htm and tz-link.htm have been renamed to
    tz-art.html and tz-link.html, respectively, for consistency with
    other file names and to simplify web server configuration.
