# @(#)Makefile.sparc	8.1 (Berkeley) 7/19/93
# Makefile for 4.4 BSD
#
# This makefile is constructed from a machine description:
#	config machineid
# Most changes should be made in the machine description
#	/sys/conf/``machineid''
# after which you should do
#	 config machineid
# Machine generic makefile changes should be made in
#	/sys/conf/Makefile.``machinetype''
# after which config should be rerun for all machines of that type.
#
# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
#	IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
#
# -DTRACE	compile in kernel tracing hooks
# -DQUOTA	compile in file system quotas

# DEBUG is set to -g if debugging.
# PROF is set to -pg if profiling.
