Subject: [PATCH] Update configure.ac and INSTALL for a modern (1.14.1)
 automake

It seems fine to let automake symlink to its default versions
of files it wants (like 'compile' and 'test-driver'), so for
now I do that.

Maybe instead I should regenerate everything. After all most
of the autoXxx bits date from 2004.
