For this, could I remove a hack for ifconfig on m68000?

sbin/ifconfig/Makefile:
https://nxr.netbsd.org/source/xref/src/sbin/ifconfig/Makefile#35

     1  #       $NetBSD: Makefile,v 1.56 2015/05/19 08:14:38 ozaki-r Exp $
......
    35  .if ${MACHINE_ARCH} == "m68000"
    36  # XXX workaround for gcc -O1 bug (PR bin/40036 and toolchain/40066)
    37  COPTS.ifconfig.c+= -fno-loop-optimize
    38  .endif

You wrote in toolchain/40066 (http://gnats.netbsd.org/40066) as

Moreover, -fno-loop-optimize is ignored by recent versions of GCC:

external/gpl3/gcc/dist/gcc/ChangeLog-2010

 15637          fstrength-reduce, ftree-store-ccp, ftree-store-copy-prop,
 15638          ftree-salias): Mark Ignore.

So, can I think that the problem has already gone?

Thanks,
