freebsd/sys/conf/Makefile.i386
Bruce Evans d0c8f50566 Don't define KERNEL for compiling genassym. The prototype for the system
printf() is inconsistent with the prototype for the library printf() and
gets declared if DIAGNOSTIC is defined because <vm/vm_page.h> includes
<sys/systm.h>.

# Makefile for FreeBSD
#
# This makefile is constructed from a machine description:
# config machineid
# Most changes should be made in the machine description
# /sys/i386/conf/``machineid''
# after which you should do
# config machineid
# Generic makefile changes should be made in
# /sys/i386/conf/Makefile.i386
# after which config should be rerun for all machines.
#
# N.B.: NO DEPENDENCIES ON FOLLOWING FLAGS ARE INVISIBLE 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
