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. 227# 228# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 229# out by the National Institute of Standards and Technology 230# which claims to test C and Posix conformance. If you want to pass PCTS, add 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 1 239# falls on a Friday, Saturday, or Sunday. 240 241CFLAGS= 242 243# Linker flags.
