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

19# DEBUG is set to -g by config if debugging is requested (config -g).
20# PROF is set to -pg by config if profiling is requested (config -p).
