tv b21bfbde11 Add -Wno-main conditional on compiler being gcc 2.8 or egcs. (This adds
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)

# Makefile for NetBSD
#
# This makefile is constructed from a machine description:
# config machineid
# Most changes should be made in the machine description
# /sys/arch/powerpc/conf/``machineid''
# after which you should do
# config machineid
# Machine generic makefile changes should be made in
# /sys/arch/powerpc/conf/Makefile.powerpc
# 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
#
.SUFFIXES: .S .c .o
# DEBUG is set to -g if debugging.
