6: # This makefile is constructed from a machine description:
7: # config machineid
8: # Most changes should be made in the machine description
9: # /sys/arch/sparc/conf/``machineid''
10: # after which you should do
11: # config machineid
12: # Machine generic makefile changes should be made in
13: # /sys/arch/sparc/conf/Makefile.sparc
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

20: # -DQUOTA compile in file system quotas

22: # DEBUG is set to -g if debugging.
