Otherwise, the functions 367 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 368 # time library, and if STD_INSPIRED is also defined to nonzero the functions 369 # "posix2time_z" and "time2posix_z" are added as well. 370 # The functions ending in "_z" (or "_rz") are like their unsuffixed 371 # (or suffixed-by-"_r") counterparts, except with an extra first 372 # argument of opaque type timezone_t that specifies the timezone. 373 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 374 # 375 # If you want to allocate state structures in localtime, add 376 # -DALL_STATE 377 # to the end of the "CFLAGS=" line.
