# Makefile for NetBSD

# This makefile is constructed from a machine description:
|
|
# config machineid
|
|
# Most changes should be made in the machine description
|
|
# /sys/arch/vax/conf/``machineid''
|
|
# after which you should do
|
|
# config machineid
|
|
# Machine generic makefile changes should be made in
|
|
# /sys/arch/vax/conf/Makefile.vax
|
|
# 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 if debugging.
|
|
# PROF is set to -pg if profiling.
