Not easily.  I have no interest in supporting old versions of Automake,
given that Automake is only needed for developers (you don’t need it
when building from a tarball), and developers can figure out how to
install the right version.  :-)

Hmm that looks good.

Could you run this from the build directory:

  rm -rf test-tmp && umask 0022 && make check

With umask == 0002, the daemon can end up creating group-writable files,
which then triggers the above error.
