 239 # If your system has a "GMT offset" field in its "struct tm"s

 241 # add the name to a define such as
 242 #       -DTM_GMTOFF=tm_gmtoff
 243 # to the end of the "CFLAGS=" line.  If not defined, the code attempts to
 244 # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
 245 # Similarly, if your system has a "zone abbreviation" field, define
 246 #       -DTM_ZONE=tm_zone
 247 # and define NO_TM_ZONE to suppress any guessing.  These two fields are not
 248 # required by POSIX, but are widely available on GNU/Linux and BSD systems.
 249 #
 250 # The next batch of options control support for external variables
 251 # exported by tzcode.  In practice these variables are less useful
 252 # than TM_GMTOFF and TM_ZONE.  However, most of them are standardized.
 253 # #
 254 # # To omit or support the external variable "tzname", add one of:
 255 # #     -DHAVE_TZNAME=0
 256 # #     -DHAVE_TZNAME=1
 257 # # to the "CFLAGS=" line.  "tzname" is required by POSIX 1988 and later.
 258 # # If not defined, the code attempts to guess HAVE_TZNAME from other macros.
 259 # # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
 260 # # crashes when combined with some platforms' standard libraries,
 261 # # presumably due to memory allocation issues.
 262 # #
 263 # # To omit or support the external variables "timezone" and "daylight", add
 264 # #     -DUSG_COMPAT=0
 265 # #     -DUSG_COMPAT=1
 266 # # to the "CFLAGS=" line; "timezone" and "daylight" are inspired by
 267 # # Unix Systems Group code and are required by POSIX 2008 (with XSI) and later.
 268 # # If not defined, the code attempts to guess USG_COMPAT from other macros.
 269 # #
 270 # # To support the external variable "altzone", add
 271 # #     -DALTZONE
 272 # # to the end of the "CFLAGS=" line; although "altzone" appeared in
 273 # # System V Release 3.1 it has not been standardized.
 274 #
 275 # If you want functions that were inspired by early versions of X3J11's work,
 276 # add
 277 #       -DSTD_INSPIRED
 278 # to the end of the "CFLAGS=" line.  This arranges for the functions
 279 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
 280 # "posix2time", and "time2posix" to be added to the time conversion library.
 281 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
 282 # time (rather than the time specified in the TZ environment variable)
 283 # to be used.
 284 # "offtime" is like "gmtime" except that it accepts a second (long) argument
 285 # that gives an offset to add to the time_t when converting it.
 286 # "timelocal" is equivalent to "mktime".
 287 # "timegm" is like "timelocal" except that it turns a struct tm into
 288 # a time_t using UT (rather than local time as "timelocal" does).
 289 # "timeoff" is like "timegm" except that it accepts a second (long) argument
 290 # that gives an offset to use when converting to a time_t.
 291 # "posix2time" and "time2posix" are described in an included manual page.
 292 # X3J11's work does not describe any of these functions.
 293 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
 294 # These functions may well disappear in future releases of the time
 295 # conversion package.
 296 #
 297 # If you don't want functions that were inspired by NetBSD, add
 298 #       -DNETBSD_INSPIRED=0
 299 # to the end of the "CFLAGS=" line.  Otherwise, the functions
 300 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
 301 # time library, and if STD_INSPIRED is also defined the functions
 302 # "posix2time_z" and "time2posix_z" are added as well.
 303 # The functions ending in "_z" (or "_rz") are like their unsuffixed
 304 # (or suffixed-by-"_r") counterparts, except with an extra first
 305 # argument of opaque type timezone_t that specifies the time zone.
 306 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
 307 #
 308 # If you want to allocate state structures in localtime, add
