 264 # to the end of the "CFLAGS=" line.  If not defined, the code attempts to
 265 # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
 266 # Similarly, if your system has a "zone abbreviation" field, define
 267 #       -DTM_ZONE=tm_zone
 268 # and define NO_TM_ZONE to suppress any guessing.  These two fields are not
 269 # required by POSIX, but are widely available on GNU/Linux and BSD systems.
 270 #
 271 # The next batch of options control support for external variables
 272 # exported by tzcode.  In practice these variables are less useful
 273 # than TM_GMTOFF and TM_ZONE.  However, most of them are standardized.
 274 # #
 275 # # To omit or support the external variable "tzname", add one of:
 276 # #     -DHAVE_TZNAME=0
 277 # #     -DHAVE_TZNAME=1
 278 # # to the "CFLAGS=" line.  "tzname" is required by POSIX 1988 and later.
 279 # # If not defined, the code attempts to guess HAVE_TZNAME from other macros.
 280 # # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
 281 # # crashes when combined with some platforms' standard libraries,
 282 # # presumably due to memory allocation issues.
 283 # #
 284 # # To omit or support the external variables "timezone" and "daylight", add
 285 # #     -DUSG_COMPAT=0
 286 # #     -DUSG_COMPAT=1
 287 # # to the "CFLAGS=" line; "timezone" and "daylight" are inspired by
 288 # # Unix Systems Group code and are required by POSIX 2008 (with XSI) and later.
 289 # # If not defined, the code attempts to guess USG_COMPAT from other macros.
 290 # #
 291 # # To support the external variable "altzone", add
 292 # #     -DALTZONE
 293 # # to the end of the "CFLAGS=" line; although "altzone" appeared in
 294 # # System V Release 3.1 it has not been standardized.

 296 # If you want functions that were inspired by early versions of X3J11's work,
 297 # add
 298 #       -DSTD_INSPIRED
 299 # to the end of the "CFLAGS=" line.  This arranges for the functions
 300 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
 301 # "posix2time", and "time2posix" to be added to the time conversion library.
 302 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
 303 # time (rather than the timezone specified in the TZ environment variable)
 304 # to be used.
 305 # "offtime" is like "gmtime" except that it accepts a second (long) argument
 306 # that gives an offset to add to the time_t when converting it.
 307 # "timelocal" is equivalent to "mktime".
 308 # "timegm" is like "timelocal" except that it turns a struct tm into
 309 # a time_t using UT (rather than local time as "timelocal" does).
 310 # "timeoff" is like "timegm" except that it accepts a second (long) argument
 311 # that gives an offset to use when converting to a time_t.
 312 # "posix2time" and "time2posix" are described in an included manual page.
 313 # X3J11's work does not describe any of these functions.
 314 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
 315 # These functions may well disappear in future releases of the time
 316 # conversion package.
 317 #
 318 # If you don't want functions that were inspired by NetBSD, add
 319 #       -DNETBSD_INSPIRED=0
 320 # to the end of the "CFLAGS=" line.  Otherwise, the functions
 321 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
 322 # time library, and if STD_INSPIRED is also defined the functions
 323 # "posix2time_z" and "time2posix_z" are added as well.
 324 # The functions ending in "_z" (or "_rz") are like their unsuffixed
 325 # (or suffixed-by-"_r") counterparts, except with an extra first
 326 # argument of opaque type timezone_t that specifies the timezone.
 327 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
 328 #
