2# Makefile for 4.4 BSD
3#
4# This makefile is constructed from a machine description:
5#	config machineid
6# Most changes should be made in the machine description
7#	/sys/conf/``machineid''
8# after which you should do
9#	 config machineid
10# Machine generic makefile changes should be made in
11#	/sys/conf/Makefile.``machinetype''
12# after which config should be rerun for all machines of that type.
13#
14# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
15#	IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
16#
17# -DTRACE	compile in kernel tracing hooks
18# -DQUOTA	compile in file system quotas
