#
# Makefile for Sun-4m SunOS
#
# 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.src
# 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
#
# different compilers decide differently on
# whether to define sun4 and sun4m ... so force
# the issue. also, since we compile sun4m kernels
# on sun4 machines, force $(ARCH) to sun4m. this
# goes away when we stop building sun4m kernels
# on lisbon and dtlab ...
#ARCH:sh = arch -k
ARCH=sun4m
USER:sh = arch
ARCHF=-U$(USER) -D$(ARCH)
