This arrange for "timezone" and "daylight" 164 # variables to be kept up-to-date by the time conversion functions. Neither 165 # "timezone" nor "daylight" is described in X3J11's work. 166 # 167 # If your system has a "GMT offset" field in its "struct tm"s 168 # (or if you decide to add such a field in your system's "time.h" file), 169 # add the name to a define such as 170 # -DTM_GMTOFF=tm_gmtoff 171 # to the end of the "CFLAGS=" line. If not defined, the code attempts to 172 # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this. 173 # Similarly, if your system has a "zone abbreviation" field, define 174 # -DTM_ZONE=tm_zone 175 # and define NO_TM_ZONE to suppress any guessing. These two fields are not 176 # required by POSIX, but are widely available on GNU/Linux and BSD systems. 177 # 178 # If you want functions that were inspired by early versions of X3J11's work, 179 # add 180 # -DSTD_INSPIRED 181 # to the end of the "CFLAGS=" line. This arranges for the functions 182 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 183 # "posix2time", and "time2posix" to be added to the time conversion library. 184 # "tzsetwall" is like "tzset" except that it arranges for local wall clock 185 # time (rather than the time specified in the TZ environment variable) 186 # to be used. 187 # "offtime" is like "gmtime" except that it accepts a second (long) argument 188 # that gives an offset to add to the time_t when converting it. 189 # "timelocal" is equivalent to "mktime". 190 # "timegm" is like "timelocal" except that it turns a struct tm into 191 # a time_t using UT (rather than local time as "timelocal" does). 192 # "timeoff" is like "timegm" except that it accepts a second (long) argument 193 # that gives an offset to use when converting to a time_t. 194 # "posix2time" and "time2posix" are described in an included manual page. 195 # X3J11's work does not describe any of these functions. 196 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 197 # These functions may well disappear in future releases of the time 198 # conversion package. 199 # 200 # If you don't want functions that were inspired by NetBSD, add 201 # -DNETBSD_INSPIRED=0 202 # to the end of the "CFLAGS=" line. Otherwise, the functions 203 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 204 # time library, and if STD_INSPIRED is also defined the functions 205 # "posix2time_z" and "time2posix_z" are added as well. 206 # The functions ending in "_z" (or "_rz") are like their unsuffixed 207 # (or suffixed-by-"_r") counterparts, except with an extra first 208 # argument of opaque type timezone_t that specifies the time zone. 209 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 210 # 211 # If you want to allocate state structures in localtime, add 212 # -DALL_STATE 213 # to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 214 # 215 # If you want an "altzone" variable (a la System V Release 3.1), add 216 # -DALTZONE 217 # to the end of the "CFLAGS=" line. 218 # This variable is not described in X3J11's work. 219 # 220 # NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 221 # out by the National Institute of Standards and Technology 222 # which claims to test C and Posix conformance. If you want to pass PCTS, add 223 # -DPCTS 224 # to the end of the "CFLAGS=" line. 225 # 226 # If you want strict compliance with XPG4 as of 1994-04-09, add 227 # -DXPG4_1994_04_09 228 # to the end of the "CFLAGS=" line. This causes "strftime" to always return 229 # 53 as a week number (rather than 52 or 53) for those days in January that 230 # before the first Monday in January when a "%V" format is used and January 1 231 # falls on a Friday, Saturday, or Sunday. 232 233 CFLAGS= 234 235 # Linker flags.
