Otherwise, the functions 465 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 466 # time library, and if STD_INSPIRED is also defined to nonzero the functions 467 # "posix2time_z" and "time2posix_z" are added as well. 468 # The functions ending in "_z" (or "_rz") are like their unsuffixed 469 # (or suffixed-by-"_r") counterparts, except with an extra first 470 # argument of opaque type timezone_t that specifies the timezone. 471 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 472 # 473 # If you want to allocate state structures in localtime, add 474 # -DALL_STATE 475 # to the end of the "CFLAGS=" line.
