Also, that particular problem is solved by newer versions
of autoconf, so in the best of all possible worlds, you
just need to have autoconf-2.53 or later installed,
and type
before running configure.   That only works sometimes, though,
since sometimes needs to be fixed a little bit to
work with the new autoconf.
