 These macros are taken from the autoconf archive at

-
-    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.
