dnl Certain portions of the Autoconf source text are designed to be copied
dnl (in certain cases, depending on the input) into the output of
dnl Autoconf. We call these the "data" portions. The rest of the Autoconf
dnl source text consists of comments plus executable code that decides which

dnl
dnl This special exception to the GPL applies to versions of Autoconf
dnl released by the Free Software Foundation. When you make and
dnl distribute a modified version of Autoconf, you may extend this special
dnl exception to the GPL to apply to your modified version as well, *unless*
dnl your modified version has the potential to copy into its output some
dnl of the text that was the non-data portion of the version that you started
dnl with. (In other words, unless your change moves or copies text from
dnl the non-data portions to the data portions.) If your modification has
dnl such potential, you must delete any notice of this special exception
dnl to the GPL from your modified version.

dnl macros. We don't use this macro to define some frequently called
