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

19: # -DQUOTA compile in file system quotas

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