Otherwise, the functions 206# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 207# time library, and if STD_INSPIRED is also defined the functions 208# "posix2time_z" and "time2posix_z" are added as well. 209# The functions ending in "_z" (or "_rz") are like their unsuffixed 210# (or suffixed-by-"_r") counterparts, except with an extra first 211# argument of opaque type timezone_t that specifies the time zone. 212# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 213# 214# If you want to allocate state structures in localtime, add 215# -DALL_STATE 216# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 217# 218# If you want an "altzone" variable (a la System V Release 3.1), add 219# -DALTZONE 220# to the end of the "CFLAGS=" line. 221# This variable is not described in X3J11's work. 222# 223# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 224# out by the National Institute of Standards and Technology 225# which claims to test C and Posix conformance.
