This arrange for "timezone" and "daylight" 169# variables to be kept up-to-date by the time conversion functions. Neither 170# "timezone" nor "daylight" is described in X3J11's work. 171# 172# If your system has a "GMT offset" field in its "struct tm"s 173# (or if you decide to add such a field in your system's "time.h" file), 174# add the name to a define such as 175# -DTM_GMTOFF=tm_gmtoff 176# to the end of the "CFLAGS=" line. If not defined, the code attempts to 177# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this. 178# Similarly, if your system has a "zone abbreviation" field, define 179# -DTM_ZONE=tm_zone 180# and define NO_TM_ZONE to suppress any guessing. These two fields are not 181# required by POSIX, but are widely available on GNU/Linux and BSD systems. 182# 183# If you want functions that were inspired by early versions of X3J11's work, 184# add 185# -DSTD_INSPIRED 186# to the end of the "CFLAGS=" line. This arranges for the functions 187# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 188# "posix2time", and "time2posix" to be added to the time conversion library. 189# "tzsetwall" is like "tzset" except that it arranges for local wall clock 190# time (rather than the time specified in the TZ environment variable) 191# to be used. 192# "offtime" is like "gmtime" except that it accepts a second (long) argument 193# that gives an offset to add to the time_t when converting it. 194# "timelocal" is equivalent to "mktime". 195# "timegm" is like "timelocal" except that it turns a struct tm into 196# a time_t using UT (rather than local time as "timelocal" does). 197# "timeoff" is like "timegm" except that it accepts a second (long) argument 198# that gives an offset to use when converting to a time_t. 199# "posix2time" and "time2posix" are described in an included manual page. 200# X3J11's work does not describe any of these functions. 201# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 202# These functions may well disappear in future releases of the time 203# conversion package. 204# 205# If you don't want functions that were inspired by NetBSD, add 206# -DNETBSD_INSPIRED=0 207# to the end of the "CFLAGS=" line. Otherwise, the functions 208# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 209# time library, and if STD_INSPIRED is also defined the functions 210# "posix2time_z" and "time2posix_z" are added as well. 211# The functions ending in "_z" (or "_rz") are like their unsuffixed 212# (or suffixed-by-"_r") counterparts, except with an extra first 213# argument of opaque type timezone_t that specifies the time zone. 214# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 215# 216# If you want to allocate state structures in localtime, add 217# -DALL_STATE 218# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 219# 220# If you want an "altzone" variable (a la System V Release 3.1), add 221# -DALTZONE 222# to the end of the "CFLAGS=" line. 223# This variable is not described in X3J11's work. 224# 225# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 226# out by the National Institute of Standards and Technology 227# which claims to test C and Posix conformance. If you want to pass PCTS, add 228# -DPCTS 229# to the end of the "CFLAGS=" line. 230# 231# If you want strict compliance with XPG4 as of 1994-04-09, add 232# -DXPG4_1994_04_09 233# to the end of the "CFLAGS=" line. This causes "strftime" to always return 234# 53 as a week number (rather than 52 or 53) for those days in January that 235# before the first Monday in January when a "%V" format is used and January 1 236# falls on a Friday, Saturday, or Sunday. 237 238CFLAGS= 239 240# Linker flags.
