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