"confifure"? Did you mean confiture? Or maybe configure? ;-)

Those m4 quoting rules just always make me nervous... So I've had a look
about everywhere in autoconf-archive, and the least we can say it's
they're not uniform... :-(  I could see that level of quotation in other
parts of autoconf-archive, so Ok.

Anyway, this restores the code to the working states it was in before
the bad changeset, and fixes the issue.

So, given the above;
