Otherwise, the functions 323# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 324# time library, and if STD_INSPIRED is also defined the functions 325# "posix2time_z" and "time2posix_z" are added as well. 326# The functions ending in "_z" (or "_rz") are like their unsuffixed 327# (or suffixed-by-"_r") counterparts, except with an extra first 328# argument of opaque type timezone_t that specifies the timezone. 329# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 330# 331# If you want to allocate state structures in localtime, add 332# -DALL_STATE 333# to the end of the "CFLAGS=" line.
