Thanks.  I'll apply when I have an OK for GCC as well.

Yes, you are right, sorry about the sloppy comment.  What about if I
change it to this?

dnl The override bits of this file should be a no-op for the newest
dnl Autoconf version, which means they can be removed once the complete
dnl tree has moved to a new enough Autoconf version.
dnl
dnl The _GCC_AUTOCONF_VERSION_TEST ensures that exactly the desired
dnl Autoconf version is used.  It should be kept for consistency.
