 124 # If you want to use System V compatibility code, add

 126 # to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
 127 # variables to be kept up-to-date by the time conversion functions.  Neither
 128 # "timezone" nor "daylight" is described in X3J11's work.
 129 #
 130 # If your system has a "GMT offset" field in its "struct tm"s
 131 # (or if you decide to add such a field in your system's "time.h" file),
 132 # add the name to a define such as
 133 #       -DTM_GMTOFF=tm_gmtoff
 134 # or
 135 #       -DTM_GMTOFF=_tm_gmtoff
 136 # to the end of the "CFLAGS=" line.
 137 # Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;
 138 # in its work, use of "tm_gmtoff" is described as non-conforming.
 139 # Both Linux and BSD have done the equivalent of defining TM_GMTOFF in
 140 # their recent releases.
 141 #
 142 # If your system has a "zone abbreviation" field in its "struct tm"s
 143 # (or if you decide to add such a field in your system's "time.h" file),
 144 # add the name to a define such as
 145 #       -DTM_ZONE=tm_zone
 146 # or
 147 #       -DTM_ZONE=_tm_zone
 148 # to the end of the "CFLAGS=" line.
 149 # Neither tm_zone nor _tm_zone is described in X3J11's work;
 150 # in its work, use of "tm_zone" is described as non-conforming.
 151 # Both UCB and Sun have done the equivalent of defining TM_ZONE in
 152 # their recent releases.
 153 #
 154 # If you want functions that were inspired by early versions of X3J11's work,
 155 # add
 156 #       -DSTD_INSPIRED
 157 # to the end of the "CFLAGS=" line.  This arranges for the functions
 158 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
 159 # "posix2time", and "time2posix" to be added to the time conversion library.
 160 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
 161 # time (rather than the time specified in the TZ environment variable)
 162 # to be used.
 163 # "offtime" is like "gmtime" except that it accepts a second (long) argument
 164 # that gives an offset to add to the time_t when converting it.
 165 # "timelocal" is equivalent to "mktime".
 166 # "timegm" is like "timelocal" except that it turns a struct tm into
 167 # a time_t using UTC (rather than local time as "timelocal" does).
 168 # "timeoff" is like "timegm" except that it accepts a second (long) argument
 169 # that gives an offset to use when converting to a time_t.
 170 # "posix2time" and "time2posix" are described in an included manual page.
 171 # X3J11's work does not describe any of these functions.
 172 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
 173 # These functions may well disappear in future releases of the time
 174 # conversion package.
 175 #
 176 # If you want Source Code Control System ID's left out of object modules, add
 177 #       -DNOID
 178 # to the end of the "CFLAGS=" line.
 179 #
 180 # If you'll never want to handle solar-time-based time zones, add
 181 #       -DNOSOLAR
 182 # to the end of the "CFLAGS=" line
 183 # (and comment out the "SDATA=" line below).
 184 # This reduces (slightly) the run-time data-space requirements of
 185 # the time conversion functions; it may reduce the acceptability of your system
 186 # to folks in oil- and cash-rich places.
 187 #
 188 # If you want to allocate state structures in localtime, add
 189 #       -DALL_STATE
 190 # to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
 191 #
 192 # If you want an "altzone" variable (a la System V Release 3.1), add
 193 #       -DALTZONE
 194 # to the end of the "CFLAGS=" line.
 195 # This variable is not described in X3J11's work.
 196 #
 197 # If you want a "gtime" function (a la MACH), add
 198 #       -DCMUCS
 199 # to the end of the "CFLAGS=" line
 200 # This function is not described in X3J11's work.
 201 #
 202 # NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put
 203 # out by the National Institute of Standards and Technology
 204 # which claims to test C and Posix conformance.  If you want to pass PCTS, add
 205 #       -DPCTS
 206 # to the end of the "CFLAGS=" line.
 207 #
 208 # If you want strict compliance with XPG4 as of 1994-04-09, add
 209 #       -DXPG4_1994_04_09
 210 # to the end of the "CFLAGS=" line.  This causes "strftime" to always return
 211 # 53 as a week number (rather than 52 or 53) for those days in January that
 212 # before the first Monday in January when a "%V" format is used and January 1
 213 # falls on a Friday, Saturday, or Sunday.
