# Makefile for NetBSD
#
# This makefile is constructed from a machine description:
# config machineid
# Most changes should be made in the machine description
# /sys/arch/sun3/conf/``machineid''
# after which you should do
1996-02-02 23:08:17 +03:00
# config machineid
# Machine generic makefile changes should be made in
# /sys/arch/sun3/conf/Makefile.sun3
# after which config should be rerun for all machines of that type.
#
# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
# IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
#
# -DTRACE compile in kernel tracing hooks
# -DQUOTA compile in file system quotas
