28# (When a POSIX-style environment variable is handled, the rules in the

30# times; the environment variable itself specifies UT offsets of standard and

129#  -DNO_RUN_TIME_WARNINGS_ABOUT_YEAR_2000_PROBLEMS_THANK_YOU=1
130#	if you do not want run time warnings about formats that may cause
131#	year 2000 grief
132#  -DTHREAD_SAFE=1 to make localtime.c thread-safe, as POSIX requires;
133#	not needed by the main-program tz code, which is single-threaded.
134#	Append other compiler flags as needed, e.g., -pthread on GNU/Linux.
135#  -Dtime_tz=\"T\" to use T as the time_t type, rather than the system time_t
136#  -DTZ_DOMAIN=\"foo\" to use "foo" for gettext domain name; default is "tz"

165# If you want to use System V compatibility code, add
166#	-DUSG_COMPAT
167# to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
168# variables to be kept up-to-date by the time conversion functions.  Neither
169# "timezone" nor "daylight" is described in X3J11's work.
170#
171# If your system has a "GMT offset" field in its "struct tm"s
172# (or if you decide to add such a field in your system's "time.h" file),
173# add the name to a define such as
174#	-DTM_GMTOFF=tm_gmtoff
175# to the end of the "CFLAGS=" line.  If not defined, the code attempts to
176# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
177# Similarly, if your system has a "zone abbreviation" field, define
178#	-DTM_ZONE=tm_zone
179# and define NO_TM_ZONE to suppress any guessing.  These two fields are not
180# required by POSIX, but are widely available on GNU/Linux and BSD systems.
181#
182# If you want functions that were inspired by early versions of X3J11's work,
183# add
184#	-DSTD_INSPIRED
185# to the end of the "CFLAGS=" line.  This arranges for the functions
186# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
187# "posix2time", and "time2posix" to be added to the time conversion library.
188# "tzsetwall" is like "tzset" except that it arranges for local wall clock
189# time (rather than the time specified in the TZ environment variable)
190# to be used.
191# "offtime" is like "gmtime" except that it accepts a second (long) argument
192# that gives an offset to add to the time_t when converting it.
193# "timelocal" is equivalent to "mktime".
194# "timegm" is like "timelocal" except that it turns a struct tm into
195# a time_t using UT (rather than local time as "timelocal" does).
196# "timeoff" is like "timegm" except that it accepts a second (long) argument
197# that gives an offset to use when converting to a time_t.
198# "posix2time" and "time2posix" are described in an included manual page.
199# X3J11's work does not describe any of these functions.
200# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
201# These functions may well disappear in future releases of the time
202# conversion package.
203#
204# If you don't want functions that were inspired by NetBSD, add
205#	-DNETBSD_INSPIRED=0
206# to the end of the "CFLAGS=" line.  Otherwise, the functions
207# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
208# time library, and if STD_INSPIRED is also defined the functions
209# "posix2time_z" and "time2posix_z" are added as well.
210# The functions ending in "_z" (or "_rz") are like their unsuffixed
211# (or suffixed-by-"_r") counterparts, except with an extra first
212# argument of opaque type timezone_t that specifies the time zone.
213# "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
214#
215# If you want to allocate state structures in localtime, add
216#	-DALL_STATE
217# to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
218#
219# If you want an "altzone" variable (a la System V Release 3.1), add
220#	-DALTZONE
221# to the end of the "CFLAGS=" line.
222# This variable is not described in X3J11's work.
223#

227#	-DPCTS
228# to the end of the "CFLAGS=" line.
229#
230# If you want strict compliance with XPG4 as of 1994-04-09, add
231#	-DXPG4_1994_04_09
232# to the end of the "CFLAGS=" line.  This causes "strftime" to always return
233# 53 as a week number (rather than 52 or 53) for those days in January that
234# before the first Monday in January when a "%V" format is used and January 1
