+# to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"

+# If you want functions that were inspired by early versions of X3J11's work,

+# 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 UTC (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.
+# None of these functions are described in X3J11's current work.
+# 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 want Source Code Control System ID's left out of object modules, add
+#	-DNOID
+# to the end of the "CFLAGS=" line.
+#
+# If you'll never want to handle solar-time-based time zones, add
+#	-DNOSOLAR
+# to the end of the "CFLAGS=" line
+# (and comment out the "SDATA=" line below).
+# This reduces (slightly) the run-time data-space requirements of
+# the time conversion functions; it may reduce the acceptability of your system
+# to folks in oil- and cash-rich places.
+#
+# 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 an "altzone" variable (a la System V Release 3.1), add
+#	-DALTZONE
+# to the end of the "CFLAGS=" line.
+# This variable is not described in X3J11's work.
+#
+# If you want a "gtime" function (a la MACH), add
+#	-DCMUCS
+# to the end of the "CFLAGS=" line
+# This function is not described in X3J11's work.
