4# Makefile for NetBSD
5#
6# This makefile is constructed from a machine description:
7#	config machineid
8# Most changes should be made in the machine description
9#	/sys/conf/``machineid''
10# after which you should do
11#	 config machineid
12# Machine generic makefile changes should be made in
13#	/sys/conf/Makefile.``machinetype''
14# after which config should be rerun for all machines of that type.
15#
16# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
17#	IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
18#
19# -DTRACE	compile in kernel tracing hooks
20# -DQUOTA	compile in file system quotas
21#
22# For cross development, uncomment XINC, and
23# copy a few things from NetBSD:/usr/include
24# into compile/xinc : nlist.h setjmp.h stab.h
