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

132#	year 2000 grief
133#  -Dssize_t=long on ancient hosts that lack ssize_t
134#  -DTHREAD_SAFE=1 to make localtime.c thread-safe, as POSIX requires;

136#	Append other compiler flags as needed, e.g., -pthread on GNU/Linux.
137#  -Dtime_tz=\"T\" to use T as the time_t type, rather than the system time_t

167# If you want to use System V compatibility code, add
168#	-DUSG_COMPAT
169# to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
170# variables to be kept up-to-date by the time conversion functions.  Neither
171# "timezone" nor "daylight" is described in X3J11's work.
172#
173# If your system has a "GMT offset" field in its "struct tm"s
174# (or if you decide to add such a field in your system's "time.h" file),
175# add the name to a define such as
176#	-DTM_GMTOFF=tm_gmtoff
177# to the end of the "CFLAGS=" line.  If not defined, the code attempts to
178# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
179# Similarly, if your system has a "zone abbreviation" field, define
180#	-DTM_ZONE=tm_zone
181# and define NO_TM_ZONE to suppress any guessing.  These two fields are not
182# required by POSIX, but are widely available on GNU/Linux and BSD systems.
183#
184# If you want functions that were inspired by early versions of X3J11's work,
185# add
186#	-DSTD_INSPIRED
187# to the end of the "CFLAGS=" line.  This arranges for the functions
188# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
189# "posix2time", and "time2posix" to be added to the time conversion library.
190# "tzsetwall" is like "tzset" except that it arranges for local wall clock
191# time (rather than the time specified in the TZ environment variable)
192# to be used.
193# "offtime" is like "gmtime" except that it accepts a second (long) argument
194# that gives an offset to add to the time_t when converting it.
195# "timelocal" is equivalent to "mktime".
196# "timegm" is like "timelocal" except that it turns a struct tm into
197# a time_t using UT (rather than local time as "timelocal" does).
198# "timeoff" is like "timegm" except that it accepts a second (long) argument
199# that gives an offset to use when converting to a time_t.
200# "posix2time" and "time2posix" are described in an included manual page.
201# X3J11's work does not describe any of these functions.
202# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
203# These functions may well disappear in future releases of the time
204# conversion package.
205#
206# If you don't want functions that were inspired by NetBSD, add
207#	-DNETBSD_INSPIRED=0
208# to the end of the "CFLAGS=" line.  Otherwise, the functions
209# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
210# time library, and if STD_INSPIRED is also defined the functions
211# "posix2time_z" and "time2posix_z" are added as well.
212# The functions ending in "_z" (or "_rz") are like their unsuffixed
213# (or suffixed-by-"_r") counterparts, except with an extra first
214# argument of opaque type timezone_t that specifies the time zone.
215# "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
216#
217# If you want to allocate state structures in localtime, add
218#	-DALL_STATE
219# to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
220#
221# If you want an "altzone" variable (a la System V Release 3.1), add
222#	-DALTZONE
223# to the end of the "CFLAGS=" line.
224# This variable is not described in X3J11's work.
225#

229#	-DPCTS
230# to the end of the "CFLAGS=" line.
231#
232# If you want strict compliance with XPG4 as of 1994-04-09, add
233#	-DXPG4_1994_04_09
234# to the end of the "CFLAGS=" line.  This causes "strftime" to always return
235# 53 as a week number (rather than 52 or 53) for those days in January that
236# before the first Monday in January when a "%V" format is used and January 1
