| # (When a POSIX-style environment variable is handled, the rules in the |

| # If you want to use System V compatibility code, add |
| # -DUSG_COMPAT |
| # to the end of the "CFLAGS=" line. This arrange for "timezone" and "daylight" |
| # variables to be kept up-to-date by the time conversion functions. Neither |
| # "timezone" nor "daylight" is described in X3J11's work. |
| # |
| # If your system has a "GMT offset" field in its "struct tm"s |
| # (or if you decide to add such a field in your system's "time.h" file), |
| # add the name to a define such as |
| # -DTM_GMTOFF=tm_gmtoff |
| # or |
| # -DTM_GMTOFF=_tm_gmtoff |
| # to the end of the "CFLAGS=" line. |
| # Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work; |
| # in its work, use of "tm_gmtoff" is described as non-conforming. |
| # Both Linux and BSD have done the equivalent of defining TM_GMTOFF in |
| # their recent releases. |
| # |
| # If your system has a "zone abbreviation" field in its "struct tm"s |
| # (or if you decide to add such a field in your system's "time.h" file), |
| # add the name to a define such as |
| # -DTM_ZONE=tm_zone |
| # or |
| # -DTM_ZONE=_tm_zone |
| # to the end of the "CFLAGS=" line. |
| # Neither tm_zone nor _tm_zone is described in X3J11's work; |
| # in its work, use of "tm_zone" is described as non-conforming. |
| # Both UCB and Sun have done the equivalent of defining TM_ZONE in |
| # their recent releases. |
| # |
| # If you want functions that were inspired by early versions of X3J11's work, |
| # add |
| # -DSTD_INSPIRED |
| # to the end of the "CFLAGS=" line. This arranges for the functions |
| # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", |
| # "posix2time", and "time2posix" to be added to the time conversion library. |
| # "tzsetwall" is like "tzset" except that it arranges for local wall clock |
| # time (rather than the time specified in the TZ environment variable) |
| # to be used. |
| # "offtime" is like "gmtime" except that it accepts a second (long) argument |
| # that gives an offset to add to the time_t when converting it. |
| # "timelocal" is equivalent to "mktime". |
| # "timegm" is like "timelocal" except that it turns a struct tm into |
| # a time_t using UTC (rather than local time as "timelocal" does). |
| # "timeoff" is like "timegm" except that it accepts a second (long) argument |
| # that gives an offset to use when converting to a time_t. |
| # "posix2time" and "time2posix" are described in an included manual page. |
| # X3J11's work does not describe any of these functions. |
| # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. |
| # These functions may well disappear in future releases of the time |
| # conversion package. |
| # |
| # If you want Source Code Control System ID's left out of object modules, add |
| # -DNOID |
| # to the end of the "CFLAGS=" line. |
| # |
| # If you'll never want to handle solar-time-based time zones, add |
| # -DNOSOLAR |
| # to the end of the "CFLAGS=" line |
| # (and comment out the "SDATA=" line below). |
| # This reduces (slightly) the run-time data-space requirements of |
| # the time conversion functions; it may reduce the acceptability of your system |
| # to folks in oil- and cash-rich places. |
| # |
| # If you want to allocate state structures in localtime, add |
| # -DALL_STATE |
| # to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. |
| # |
| # If you want an "altzone" variable (a la System V Release 3.1), add |
| # -DALTZONE |
| # to the end of the "CFLAGS=" line. |
| # This variable is not described in X3J11's work. |
| # |
| # If you want a "gtime" function (a la MACH), add |
| # -DCMUCS |
| # to the end of the "CFLAGS=" line |
| # This function is not described in X3J11's work. |
| # |
| # NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put |
| # out by the National Institute of Standards and Technology |
| # which claims to test C and Posix conformance. If you want to pass PCTS, add |
| # -DPCTS |
| # to the end of the "CFLAGS=" line. |
| # |
| # If you want strict compliance with XPG4 as of 1994-04-09, add |
| # -DXPG4_1994_04_09 |
| # to the end of the "CFLAGS=" line. This causes "strftime" to always return |
| # 53 as a week number (rather than 52 or 53) for those days in January that |
