# Makefile for 4.4 BSD

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