15# This makefile is constructed from a machine description:
16#	config machineid
17# Most changes should be made in the machine description
18#	/sys/arch/sparc64/conf/``machineid''
19# after which you should do
20#	config machineid
21# Machine generic makefile changes should be made in
22#	/sys/arch/sparc64/conf/Makefile.sparc64
23# after which config should be rerun for all machines of that type.
24#
25# To specify debugging, add the config line: makeoptions DEBUG="-g"
26# A better way is to specify -g only for a few files.
27#

33# will fail.
