Subject: [PATCH 12/12] configure.ac: remove the --enable-warnings flag.

This flag simply adds "-Wall" to $CXXFLAGS when it is enabled and the
value of the $GCC variable is true. Given how easy it is to run

  CXXFLAGS=-Wall ./configure

(which uses standard knowledge) compared to

  ./configure --enable-warnings

(which does not), I don't think this flag warrants the extra complexity
in configure.ac. This commit removes the option.
