This arrange for "timezone" and "daylight" 170 # variables to be kept up-to-date by the time conversion functions. Neither 171 # "timezone" nor "daylight" is described in X3J11's work. 172 # 173 # If your system has a "GMT offset" field in its "struct tm"s 174 # (or if you decide to add such a field in your system's "time.h" file), 175 # add the name to a define such as 176 # -DTM_GMTOFF=tm_gmtoff 177 # to the end of the "CFLAGS=" line. If not defined, the code attempts to 178 # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this. 179 # Similarly, if your system has a "zone abbreviation" field, define 180 # -DTM_ZONE=tm_zone 181 # and define NO_TM_ZONE to suppress any guessing. These two fields are not 182 # required by POSIX, but are widely available on GNU/Linux and BSD systems. 183 # 184 # If you want functions that were inspired by early versions of X3J11's work, 185 # add 186 # -DSTD_INSPIRED 187 # to the end of the "CFLAGS=" line. This arranges for the functions 188 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 189 # "posix2time", and "time2posix" to be added to the time conversion library. 190 # "tzsetwall" is like "tzset" except that it arranges for local wall clock 191 # time (rather than the time specified in the TZ environment variable) 192 # to be used. 193 # "offtime" is like "gmtime" except that it accepts a second (long) argument 194 # that gives an offset to add to the time_t when converting it. 195 # "timelocal" is equivalent to "mktime". 196 # "timegm" is like "timelocal" except that it turns a struct tm into 197 # a time_t using UT (rather than local time as "timelocal" does). 198 # "timeoff" is like "timegm" except that it accepts a second (long) argument 199 # that gives an offset to use when converting to a time_t. 200 # "posix2time" and "time2posix" are described in an included manual page. 201 # X3J11's work does not describe any of these functions. 202 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 203 # These functions may well disappear in future releases of the time 204 # conversion package. 205 # 206 # If you don't want functions that were inspired by NetBSD, add 207 # -DNETBSD_INSPIRED=0 208 # to the end of the "CFLAGS=" line. Otherwise, the functions 209 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 210 # time library, and if STD_INSPIRED is also defined the functions 211 # "posix2time_z" and "time2posix_z" are added as well. 212 # The functions ending in "_z" (or "_rz") are like their unsuffixed 213 # (or suffixed-by-"_r") counterparts, except with an extra first 214 # argument of opaque type timezone_t that specifies the time zone. 215 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 216 # 217 # If you want to allocate state structures in localtime, add 218 # -DALL_STATE 219 # to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 220 # 221 # If you want an "altzone" variable (a la System V Release 3.1), add 222 # -DALTZONE 223 # to the end of the "CFLAGS=" line. 224 # This variable is not described in X3J11's work. 225 # 226 # NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 227 # out by the National Institute of Standards and Technology 228 # which claims to test C and Posix conformance. If you want to pass PCTS, add 229 # -DPCTS 230 # to the end of the "CFLAGS=" line. 231 # 232 # If you want strict compliance with XPG4 as of 1994-04-09, add 233 # -DXPG4_1994_04_09 234 # to the end of the "CFLAGS=" line. This causes "strftime" to always return 235 # 53 as a week number (rather than 52 or 53) for those days in January that 236 # before the first Monday in January when a "%V" format is used and January 1 237 # falls on a Friday, Saturday, or Sunday. 238 239 CFLAGS= 240 241 # Linker flags.
