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

231 # -DPCTS
232 # to the end of the "CFLAGS=" line.
233 #
234 # If you want strict compliance with XPG4 as of 1994-04-09, add
235 # -DXPG4_1994_04_09
236 # to the end of the "CFLAGS=" line. This causes "strftime" to always return
237 # 53 as a week number (rather than 52 or 53) for those days in January that
238 # before the first Monday in January when a "%V" format is used and January 1
