# (When a POSIX-style environment variable is handled, the rules in the
# template file are used to determine "spring forward" and "fall back" days and
# times; the environment variable itself specifies UT offsets of standard and
# summer time.)

# Add the following to the end of the "CFLAGS=" line as needed.
# -DBIG_BANG=-9999999LL if the Big Bang occurred at time -9999999 (see zic.c)
# -DHAVE_DECL_ASCTIME_R=0 if <time.h> does not declare asctime_r
# -DHAVE_DIRECT_H if mkdir needs <direct.h> (MS-Windows)
# -DHAVE_DOS_FILE_NAMES if file names have drive specifiers etc. (MS-DOS)
# -DHAVE_GETTEXT=1 if 'gettext' works (GNU, Linux, Solaris); also see LDLIBS
# -DHAVE_INCOMPATIBLE_CTIME_R=1 if your system's time.h declares
# ctime_r and asctime_r incompatibly with the POSIX standard (Solaris 8).
# -DHAVE_INTTYPES_H=1 if you have a pre-C99 compiler with "inttypes.h"
# -DHAVE_LINK=0 if your system lacks a link function
# -DHAVE_LOCALTIME_R=0 if your system lacks a localtime_r function
# -DHAVE_LOCALTIME_RZ=0 if you do not want zdump to use localtime_rz
# This defaults to 1 if a working localtime_rz seems to be available.
# localtime_rz can make zdump significantly faster, but is nonstandard.
# -DHAVE_POSIX_DECLS=0 if your system's include files do not declare
# functions like 'link' or variables like 'tzname' required by POSIX
# -DHAVE_STDINT_H=1 if you have a pre-C99 compiler with "stdint.h"
# -DHAVE_STRFTIME_L=1 if <time.h> declares locale_t and strftime_l
# This defaults to 0 if _POSIX_VERSION < 200809, 1 otherwise.
# -DHAVE_STRDUP=0 if your system lacks the strdup function
# -DHAVE_SYMLINK=0 if your system lacks the symlink function

# -DHAVE_SYS_WAIT_H=0 if your compiler lacks a "sys/wait.h"
# -DHAVE_TZSET=0 if your system lacks a tzset function
# -DHAVE_UNISTD_H=0 if your compiler lacks a "unistd.h" (Microsoft C++ 7?)
# -DNO_RUN_TIME_WARNINGS_ABOUT_YEAR_2000_PROBLEMS_THANK_YOU=1
# if you do not want run time warnings about formats that may cause
# year 2000 grief
# -Dssize_t=long on ancient hosts that lack ssize_t
# -DTHREAD_SAFE=1 to make localtime.c thread-safe, as POSIX requires;
# not needed by the main-program tz code, which is single-threaded.
# Append other compiler flags as needed, e.g., -pthread on GNU/Linux.
# -Dtime_tz=\"T\" to use T as the time_t type, rather than the system time_t
# -DTZ_DOMAIN=\"foo\" to use "foo" for gettext domain name; default is "tz"
# -DTZ_DOMAINDIR=\"/path\" to use "/path" for gettext directory;
# the default is system-supplied, typically "/usr/lib/locale"
# -DTZDEFRULESTRING=\",date/time,date/time\" to default to the specified
# -DUNINIT_TRAP=1 if reading uninitialized storage can cause problems
# other than simply getting garbage data
# -DUSE_LTZ=0 to build zdump with the system time zone library
# Also set TZDOBJS=zdump.o and CHECK_TIME_T_ALTERNATIVES= below.
# -DNO_ERROR_IN_DST_GAP=1
# if you want mktime() not to return an error in the DST gap.
# -DZIC_MAX_ABBR_LEN_WO_WARN=3
# (or some other number) to set the maximum time zone abbreviation length
# that zic will accept without a warning (the default is 6)

# If you want to use System V compatibility code, add
# -DUSG_COMPAT
# to the end of the "CFLAGS=" line. This arrange for "timezone" and "daylight"
# variables to be kept up-to-date by the time conversion functions. Neither
# "timezone" nor "daylight" is described in X3J11's work.
#
# If your system has a "GMT offset" field in its "struct tm"s
# (or if you decide to add such a field in your system's "time.h" file),
# add the name to a define such as
# -DTM_GMTOFF=tm_gmtoff
# to the end of the "CFLAGS=" line. If not defined, the code attempts to
# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
# Similarly, if your system has a "zone abbreviation" field, define
# -DTM_ZONE=tm_zone
# and define NO_TM_ZONE to suppress any guessing. These two fields are not
# required by POSIX, but are widely available on GNU/Linux and BSD systems.
#
# If you want functions that were inspired by early versions of X3J11's work,
# add
# -DSTD_INSPIRED
# to the end of the "CFLAGS=" line. This arranges for the functions
# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
# "posix2time", and "time2posix" to be added to the time conversion library.
# "tzsetwall" is like "tzset" except that it arranges for local wall clock
# time (rather than the time specified in the TZ environment variable)
# to be used.
# "offtime" is like "gmtime" except that it accepts a second (long) argument
# that gives an offset to add to the time_t when converting it.
# "timelocal" is equivalent to "mktime".
# "timegm" is like "timelocal" except that it turns a struct tm into
# a time_t using UT (rather than local time as "timelocal" does).
# "timeoff" is like "timegm" except that it accepts a second (long) argument
# that gives an offset to use when converting to a time_t.
# "posix2time" and "time2posix" are described in an included manual page.
# X3J11's work does not describe any of these functions.
# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
# These functions may well disappear in future releases of the time
# conversion package.
#
# If you don't want functions that were inspired by NetBSD, add
# -DNETBSD_INSPIRED=0
# to the end of the "CFLAGS=" line. Otherwise, the functions
# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
# time library, and if STD_INSPIRED is also defined the functions
# "posix2time_z" and "time2posix_z" are added as well.
# The functions ending in "_z" (or "_rz") are like their unsuffixed
# (or suffixed-by-"_r") counterparts, except with an extra first
# argument of opaque type timezone_t that specifies the time zone.
# "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
#
# If you want to allocate state structures in localtime, add
# -DALL_STATE
# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc.
#
# If you want an "altzone" variable (a la System V Release 3.1), add
# -DALTZONE
# to the end of the "CFLAGS=" line.
# This variable is not described in X3J11's work.
#
# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put
# out by the National Institute of Standards and Technology
# which claims to test C and Posix conformance. If you want to pass PCTS, add
# -DPCTS
# to the end of the "CFLAGS=" line.
#
# If you want strict compliance with XPG4 as of 1994-04-09, add
# -DXPG4_1994_04_09
# to the end of the "CFLAGS=" line. This causes "strftime" to always return
# 53 as a week number (rather than 52 or 53) for those days in January that
# before the first Monday in January when a "%V" format is used and January 1
# falls on a Friday, Saturday, or Sunday.
