# You may want to change this define if you're just testing the software.
# Alternatively, you can put these functions in /lib/libc.a, removing

# then add them to libc.a.

# If you're running on a System V-style system and don't want lint grief,

# If you want to use System V compatibility code, add

# If you want BSD compatibility code, add

#
# 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),

#
# If your system has a "GMT offset" field in its "struct tm"s

#
# If you want code inspired by certain emerging standards, add

#
# If you want Source Code Control System ID's left out of object modules, add

# 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

#
# If you want to allocate state structures in localtime, add

# If you want an "altzone" variable (a la System V Release 3.1), add
