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/arch/i386/conf/``machineid''
10# after which you should do
11#	 config machineid
12# Generic makefile changes should be made in
13#	/sys/arch/i386/conf/Makefile.i386
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
