#	@(#)makefile.vax	4.3	(ULTRIX)	1/31/91
#
# Makefile for ULTRIX
#
# This makefile is constructed from a machine description:
#	config machine
# Most changes should be made in the machine description
#	/sys/conf/``machineid''
# after which you should do
#	 config machineid
# Generic makefile changes should be made in
#	/sys/conf/makefile
# after which config should be rerun for all machines.
#
# 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
# -DUUDMA	compile in unibus tu58 pseudo-dma code
# -DSWABIPS	compile in code to byte swap ip packets on 3Mb/s Ethernet
#
#
#	All commands used in makefiles need to be declared as variables
