      4 # Makefile for 4.4 BSD

      6 # This makefile is constructed from a machine description:
      7 #	config machineid
      8 # Most changes should be made in the machine description
      9 #	/sys/conf/``machineid''
     10 # after which you should do
     11 #	 config machineid
     12 # Machine generic makefile changes should be made in
     13 #	/sys/conf/Makefile.``machinetype''
     14 # after which config should be rerun for all machines of that type.
     15 #
     16 # N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE VISIBLE TO MAKEFILE
     17 #	IF YOU CHANGE THE DEFINITION OF ANY OF THESE RECOMPILE EVERYTHING
     18 #
