# Explanations of flags:
#
# If you want to use System V compatibility code, add
#	-DUSG_COMPAT
# to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
# variables to be kept up-to-date by the time conversion functions.  Neither
# "timezone" nor "daylight" is described in X3J11's work.
#
# 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
# or
#	-DTM_GMTOFF=_tm_gmtoff
# to the end of the "CFLAGS=" line.
# Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;
# in its work, use of "tm_gmtoff" is described as non-conforming.
# Both Linux and BSD have done the equivalent of defining TM_GMTOFF in
# their recent releases.
#
# If your system has a "zone abbreviation" 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_ZONE=tm_zone
# or
#	-DTM_ZONE=_tm_zone
# to the end of the "CFLAGS=" line.
# Neither tm_zone nor _tm_zone is described in X3J11's work;
# in its work, use of "tm_zone" is described as non-conforming.
# Both UCB and Sun have done the equivalent of defining TM_ZONE in
# their recent releases.
#
# 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 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.
# 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 want Source Code Control System ID's left out of object modules, add
#	-DNOID
# to the end of the "CFLAGS=" line.
#
# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put
# out by the National Institute of Standards and Technology
# which claims to test C and Posix conformance.  If you want to pass PCTS, add
#	-DPCTS
# to the end of the "CFLAGS=" line.
