Otherwise, the functions 210# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 211# time library, and if STD_INSPIRED is also defined the functions 212# "posix2time_z" and "time2posix_z" are added as well. 213# The functions ending in "_z" (or "_rz") are like their unsuffixed 214# (or suffixed-by-"_r") counterparts, except with an extra first 215# argument of opaque type timezone_t that specifies the time zone. 216# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 217# 218# If you want to allocate state structures in localtime, add 219# -DALL_STATE 220# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 221# 222# If you want an "altzone" variable (a la System V Release 3.1), add 223# -DALTZONE 224# to the end of the "CFLAGS=" line. 225# This variable is not described in X3J11's work. 226# 227# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 228# out by the National Institute of Standards and Technology 229# which claims to test C and Posix conformance.
