3# Makefile for NetBSD
4#
5# This makefile is constructed from a machine description:
6#	config machineid
7# Most changes should be made in the machine description
8#	/sys/arch/mvme68k/conf/``machineid''
9# after which you should do
10#	config machineid
11# Machine generic makefile changes should be made in
12#	/sys/arch/mvme68k/conf/Makefile.mvme68k
13# after which config should be rerun for all machines of that type.
14#
15# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
16#	IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
17#
18# -DTRACE	compile in kernel tracing hooks
19# -DQUOTA	compile in file system quotas
20
21# DEBUG is set to -g if debugging.
22# PROF is set to -pg if profiling.
