This arrange for "timezone" and "daylight" 175# variables to be kept up-to-date by the time conversion functions. Neither 176# "timezone" nor "daylight" is described in X3J11's work. 177# 178# If your system has a "GMT offset" field in its "struct tm"s 179# (or if you decide to add such a field in your system's "time.h" file), 180# add the name to a define such as 181# -DTM_GMTOFF=tm_gmtoff 182# to the end of the "CFLAGS=" line. If not defined, the code attempts to 183# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this. 184# Similarly, if your system has a "zone abbreviation" field, define 185# -DTM_ZONE=tm_zone 186# and define NO_TM_ZONE to suppress any guessing. These two fields are not 187# required by POSIX, but are widely available on GNU/Linux and BSD systems. 188# 189# If you want functions that were inspired by early versions of X3J11's work, 190# add 191# -DSTD_INSPIRED 192# to the end of the "CFLAGS=" line. This arranges for the functions 193# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 194# "posix2time", and "time2posix" to be added to the time conversion library. 195# "tzsetwall" is like "tzset" except that it arranges for local wall clock 196# time (rather than the time specified in the TZ environment variable) 197# to be used. 198# "offtime" is like "gmtime" except that it accepts a second (long) argument 199# that gives an offset to add to the time_t when converting it. 200# "timelocal" is equivalent to "mktime". 201# "timegm" is like "timelocal" except that it turns a struct tm into 202# a time_t using UT (rather than local time as "timelocal" does). 203# "timeoff" is like "timegm" except that it accepts a second (long) argument 204# that gives an offset to use when converting to a time_t. 205# "posix2time" and "time2posix" are described in an included manual page. 206# X3J11's work does not describe any of these functions. 207# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 208# These functions may well disappear in future releases of the time 209# conversion package. 210# 211# If you don't want functions that were inspired by NetBSD, add 212# -DNETBSD_INSPIRED=0 213# to the end of the "CFLAGS=" line. Otherwise, the functions 214# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 215# time library, and if STD_INSPIRED is also defined the functions 216# "posix2time_z" and "time2posix_z" are added as well. 217# The functions ending in "_z" (or "_rz") are like their unsuffixed 218# (or suffixed-by-"_r") counterparts, except with an extra first 219# argument of opaque type timezone_t that specifies the time zone. 220# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 221# 222# If you want to allocate state structures in localtime, add 223# -DALL_STATE 224# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 225# 226# If you want an "altzone" variable (a la System V Release 3.1), add 227# -DALTZONE 228# to the end of the "CFLAGS=" line. 229# This variable is not described in X3J11's work. 230# 231# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 232# out by the National Institute of Standards and Technology 233# which claims to test C and Posix conformance. If you want to pass PCTS, add 234# -DPCTS 235# to the end of the "CFLAGS=" line. 236# 237# If you want strict compliance with XPG4 as of 1994-04-09, add 238# -DXPG4_1994_04_09 239# to the end of the "CFLAGS=" line. This causes "strftime" to always return 240# 53 as a week number (rather than 52 or 53) for those days in January that 241# before the first Monday in January when a "%V" format is used and January 1 242# falls on a Friday, Saturday, or Sunday. 243 244CFLAGS= 245 246# Linker flags.
