+
+As a special exception, the Free Software Foundation gives unlimited
+permission to copy, distribute and modify the configure scripts that
+are the output of Autoconf. You need not follow the terms of the GNU
+General Public License when using or distributing such scripts, even
+though portions of the text of Autoconf appear in them. The GNU
+General Public License (GPL) does govern all other use of the material
+that constitutes the Autoconf program.
+
+Certain portions of the Autoconf source text are designed to be copied
+(in certain cases, depending on the input) into the output of
+Autoconf. We call these the "data" portions. The rest of the Autoconf
+source text consists of comments plus executable code that decides
+which of the data portions to output in any given case. We call these
+comments and executable code the "non-data" portions. Autoconf never
+copies any of the non-data portions into its output.
+
+This special exception to the GPL applies to versions of Autoconf
+released by the Free Software Foundation. When you make and distribute
+a modified version of Autoconf, you may extend this special exception
+to the GPL to apply to your modified version as well, *unless* your
+modified version has the potential to copy into its output some of the
+text that was the non-data portion of the version that you started
+with. (In other words, unless your change moves or copies text from
+the non-data portions to the data portions.) If your modification has
+such potential, you must delete any notice of this special exception
+to the GPL from your modified version.
