With respect to autoconf 2.x... the generate configure is;

Copyright (C) 1992, 1993, 1994, 1995, 1996, 1998, 1999, 2000, 2001,
2002, 2003, 2004, 2005, 2006 Free Software Foundation, Inc.
This configure script is free software; the Free Software Foundation
gives unlimited permission to copy, distribute and modify it.

It has a dependency, config.sub, and libtool adds ltmain.sh, which
are GPL, with a specific exception...

# As a special exception to the GNU General Public License, if you
# distribute this file as part of a program that contains a
# configuration script generated by Autoconf, you may include it under
# the same distribution terms that you use for the rest of that program.

which is why it is no problem.  It might be good to label the NOTICE
for source (as opposed to binaries) with the copyright notice for
additional clarity, but the license itself hovers between an unlimited
license for use, and the AL, or whatever other license would apply.
