# This makefile is constructed from a machine description:
#	config machineid
# Most changes should be made in the machine description
#	/sys/arch/mvme68k/conf/``machineid''
# after which you should do
#	 config machineid
# Machine generic makefile changes should be made in
#	/sys/arch/mvme68k/conf/Makefile.mvme68k
# 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


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