AC_HELP_STRING is obsolete in autoconf 2.70 #6647
I did this
The stderr starts like this:
I expected the following
No obsolete warnings
OpenBSD-current, autoconf-2.70, automake-1.16

2.70 is claimed to "not able to maintain perfect backward compatibility with existing Autoconf scripts" which of course is terribly annoying if we want to support both newer and older versions.
