14# the time zone files, or adding it to a time zone file).
15# Alternately, if you discover you've got the wrong time zone, you can just

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

75# If you want only POSIX time, with time values interpreted as
76# seconds since the epoch (not counting leap seconds), use

84# below.  If you want both sets of data available, with leap seconds counted
85# normally, use

87# below.  POSIX mandates that leap seconds not be counted; for compatibility
88# with it, use "posix_only" or "posix_right".  Use POSIX time on systems with
89# leap smearing; this can work better than unsmeared "right" time with
90# applications that are not leap second aware, and is closer to unsmeared

110#  -DBIG_BANG=-9999999LL if the Big Bang occurred at time -9999999 (see zic.c)
111#  -DHAVE_DECL_ASCTIME_R=0 if <time.h> does not declare asctime_r
112#  -DHAVE_DIRECT_H if mkdir needs <direct.h> (MS-Windows)
113#  -DHAVE_DOS_FILE_NAMES if file names have drive specifiers etc. (MS-DOS)
114#  -DHAVE_GETTEXT=1 if 'gettext' works (e.g., GNU/Linux, FreeBSD, Solaris)
115#  -DHAVE_INCOMPATIBLE_CTIME_R=1 if your system's time.h declares
116#	ctime_r and asctime_r incompatibly with the POSIX standard
117#	(Solaris when _POSIX_PTHREAD_SEMANTICS is not defined).
118#  -DHAVE_INTTYPES_H=1 if you have a pre-C99 compiler with "inttypes.h"
119#  -DHAVE_LINK=0 if your system lacks a link function
120#  -DHAVE_LOCALTIME_R=0 if your system lacks a localtime_r function
121#  -DHAVE_LOCALTIME_RZ=0 if you do not want zdump to use localtime_rz
122#	This defaults to 1 if a working localtime_rz seems to be available.
123#	localtime_rz can make zdump significantly faster, but is nonstandard.
124#  -DHAVE_POSIX_DECLS=0 if your system's include files do not declare
125#	functions like 'link' or variables like 'tzname' required by POSIX
126#  -DHAVE_STDINT_H=1 if you have a pre-C99 compiler with "stdint.h"
127#  -DHAVE_STRFTIME_L=1 if <time.h> declares locale_t and strftime_l
128#	This defaults to 0 if _POSIX_VERSION < 200809, 1 otherwise.
129#  -DHAVE_STRDUP=0 if your system lacks the strdup function
130#  -DHAVE_SYMLINK=0 if your system lacks the symlink function
131#  -DHAVE_SYS_STAT_H=0 if your compiler lacks a "sys/stat.h"
132#  -DHAVE_SYS_WAIT_H=0 if your compiler lacks a "sys/wait.h"
133#  -DHAVE_TZSET=0 if your system lacks a tzset function
134#  -DHAVE_UNISTD_H=0 if your compiler lacks a "unistd.h" (Microsoft C++ 7?)
135#  -DEPOCH_LOCAL=1 if the 'time' function returns local time not UT
136#  -DEPOCH_OFFSET=N if the 'time' function returns a value N greater
137#	than what POSIX specifies, assuming local time is UT.
138#	For example, N is 252460800 on AmigaOS.
139#  -DNO_RUN_TIME_WARNINGS_ABOUT_YEAR_2000_PROBLEMS_THANK_YOU=1
140#	if you do not want run time warnings about formats that may cause
141#	year 2000 grief
142#  -Dssize_t=long on ancient hosts that lack ssize_t
143#  -DTHREAD_SAFE=1 to make localtime.c thread-safe, as POSIX requires;
144#	not needed by the main-program tz code, which is single-threaded.
145#	Append other compiler flags as needed, e.g., -pthread on GNU/Linux.
146#  -Dtime_tz=\"T\" to use T as the time_t type, rather than the system time_t
147#  -DTZ_DOMAIN=\"foo\" to use "foo" for gettext domain name; default is "tz"
148#  -DTZ_DOMAINDIR=\"/path\" to use "/path" for gettext directory;
149#	the default is system-supplied, typically "/usr/lib/locale"
150#  -DTZDEFRULESTRING=\",date/time,date/time\" to default to the specified
151#  -DUNINIT_TRAP=1 if reading uninitialized storage can cause problems
152#	other than simply getting garbage data
153#  -DUSE_LTZ=0 to build zdump with the system time zone library
154#	Also set TZDOBJS=zdump.o and CHECK_TIME_T_ALTERNATIVES= below.
155#  -DNO_ERROR_IN_DST_GAP=1
156#	if you want mktime() not to return an error in the DST gap.
157#  -DZIC_MAX_ABBR_LEN_WO_WARN=3
158#	(or some other number) to set the maximum time zone abbreviation length
159#	that zic will accept without a warning (the default is 6)

176# If you want to use System V compatibility code, add
177#	-DUSG_COMPAT
178# to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
179# variables to be kept up-to-date by the time conversion functions.  Neither
180# "timezone" nor "daylight" is described in X3J11's work.
181#
182# If your system has a "GMT offset" field in its "struct tm"s
183# (or if you decide to add such a field in your system's "time.h" file),
184# add the name to a define such as
185#	-DTM_GMTOFF=tm_gmtoff
186# to the end of the "CFLAGS=" line.  If not defined, the code attempts to
187# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
188# Similarly, if your system has a "zone abbreviation" field, define
189#	-DTM_ZONE=tm_zone
190# and define NO_TM_ZONE to suppress any guessing.  These two fields are not
191# required by POSIX, but are widely available on GNU/Linux and BSD systems.
192#
193# If you want functions that were inspired by early versions of X3J11's work,
194# add
195#	-DSTD_INSPIRED
196# to the end of the "CFLAGS=" line.  This arranges for the functions
197# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
198# "posix2time", and "time2posix" to be added to the time conversion library.
199# "tzsetwall" is like "tzset" except that it arranges for local wall clock
200# time (rather than the time specified in the TZ environment variable)
201# to be used.
202# "offtime" is like "gmtime" except that it accepts a second (long) argument
203# that gives an offset to add to the time_t when converting it.
204# "timelocal" is equivalent to "mktime".
205# "timegm" is like "timelocal" except that it turns a struct tm into
206# a time_t using UT (rather than local time as "timelocal" does).
207# "timeoff" is like "timegm" except that it accepts a second (long) argument
208# that gives an offset to use when converting to a time_t.
209# "posix2time" and "time2posix" are described in an included manual page.
210# X3J11's work does not describe any of these functions.
211# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
212# These functions may well disappear in future releases of the time
213# conversion package.
214#
215# If you don't want functions that were inspired by NetBSD, add
216#	-DNETBSD_INSPIRED=0
217# to the end of the "CFLAGS=" line.  Otherwise, the functions
218# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
219# time library, and if STD_INSPIRED is also defined the functions
220# "posix2time_z" and "time2posix_z" are added as well.
221# The functions ending in "_z" (or "_rz") are like their unsuffixed
222# (or suffixed-by-"_r") counterparts, except with an extra first
223# argument of opaque type timezone_t that specifies the time zone.
224# "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
225#
226# If you want to allocate state structures in localtime, add
227#	-DALL_STATE
228# to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
229#
230# If you want an "altzone" variable (a la System V Release 3.1), add
231#	-DALTZONE
232# to the end of the "CFLAGS=" line.
233# This variable is not described in X3J11's work.
234#
235# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put
236# out by the National Institute of Standards and Technology

238#	-DPCTS
239# to the end of the "CFLAGS=" line.
240#
241# If you want strict compliance with XPG4 as of 1994-04-09, add
242#	-DXPG4_1994_04_09
243# to the end of the "CFLAGS=" line.  This causes "strftime" to always return
244# 53 as a week number (rather than 52 or 53) for those days in January that
245# before the first Monday in January when a "%V" format is used and January 1
