# If your system has a "GMT offset" field in its "struct tm"s 
# (or if you decide to add such a field in your system's "time.h" file), 
# add the name to a define such as 
#       -DTM_GMTOFF=tm_gmtoff 
# to the end of the "CFLAGS=" line.  If not defined, the code attempts to 
# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this. 
# Similarly, if your system has a "zone abbreviation" field, define 
#       -DTM_ZONE=tm_zone 
# and define NO_TM_ZONE to suppress any guessing.  These two fields are not 
# required by POSIX, but are widely available on GNU/Linux and BSD systems. 
# 
# The next batch of options control support for external variables 
# exported by tzcode.  In practice these variables are less useful 
# than TM_GMTOFF and TM_ZONE.  However, most of them are standardized. 
# # 
# # To omit or support the external variable "tzname", add one of: 
# #     -DHAVE_TZNAME=0 
# #     -DHAVE_TZNAME=1 
# # to the "CFLAGS=" line.  "tzname" is required by POSIX 1988 and later. 
# # If not defined, the code attempts to guess HAVE_TZNAME from other macros. 
# # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause 
# # crashes when combined with some platforms' standard libraries, 
# # presumably due to memory allocation issues. 
# # 
# # To omit or support the external variables "timezone" and "daylight", add 
# #     -DUSG_COMPAT=0 
# #     -DUSG_COMPAT=1 
# # to the "CFLAGS=" line; "timezone" and "daylight" are inspired by 
# # Unix Systems Group code and are required by POSIX 2008 (with XSI) and later. 
# # If not defined, the code attempts to guess USG_COMPAT from other macros. 
# # 
# # To support the external variable "altzone", add 
# #     -DALTZONE 
# # to the end of the "CFLAGS=" line; although "altzone" appeared in 
# # System V Release 3.1 it has not been standardized. 
# 
# If you want functions that were inspired by early versions of X3J11's work, 
# add 
#       -DSTD_INSPIRED 
# to the end of the "CFLAGS=" line.  This arranges for the functions 
# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 
# "posix2time", and "time2posix" to be added to the time conversion library. 
# "tzsetwall" is like "tzset" except that it arranges for local wall clock 
# time (rather than the time specified in the TZ environment variable) 
# to be used. 
# "offtime" is like "gmtime" except that it accepts a second (long) argument 
# that gives an offset to add to the time_t when converting it. 
# "timelocal" is equivalent to "mktime". 
# "timegm" is like "timelocal" except that it turns a struct tm into 
# a time_t using UT (rather than local time as "timelocal" does). 
# "timeoff" is like "timegm" except that it accepts a second (long) argument 
# that gives an offset to use when converting to a time_t. 
# "posix2time" and "time2posix" are described in an included manual page. 
# X3J11's work does not describe any of these functions. 
# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 
# These functions may well disappear in future releases of the time 
# conversion package. 
# 
# If you don't want functions that were inspired by NetBSD, add 
#       -DNETBSD_INSPIRED=0 
# to the end of the "CFLAGS=" line.  Otherwise, the functions 
# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 
# time library, and if STD_INSPIRED is also defined the functions 
# "posix2time_z" and "time2posix_z" are added as well. 
# The functions ending in "_z" (or "_rz") are like their unsuffixed 
# (or suffixed-by-"_r") counterparts, except with an extra first 
# argument of opaque type timezone_t that specifies the time zone. 
# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 
# 
# If you want to allocate state structures in localtime, add 
#       -DALL_STATE 
# to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.

# If you want strict compliance with XPG4 as of 1994-04-09, add
