This is odd.  I don't get any errors on a clean rebuild.  Neither does
Ben's build-bot.  The signature of fopen_temp was changed in gnulib on
2020-06-27 so any commit later than that should not cause the issue you

Can you double check?  (do "git clean -dfx" in your source directory).

If you still think it is necessary to update gnulib again, then go ahead
and change README.Git and anything else that is necessary.  If we have
to demand an update to autoconf 2.64 I think that is not a big deal.

     Hi John,
     yes of course - but that commit d6dabe8ee is the commit that I have used 
after you changed it
     in the README.git. That commit however results in the errors mentioned 
below while the
     gnulib version 18 days later has fixed these problems.
