How about this? I haven't been following the re-licensing discussions closely (still catching up), but these files seems to be used during the build phase, and using the GPLv3 for that seems non-controversial, or?
Btw, libidn 1.0 (recently released) uses latest gnulib, and there were no license problems. I'm doing the same exercise now with gsasl, but it seems there are no conflicts there either. /Simon Index: ChangeLog =================================================================== RCS file: /sources/gnulib/gnulib/ChangeLog,v retrieving revision 1.1872 diff -u -p -r1.1872 ChangeLog --- ChangeLog 31 Jul 2007 22:34:58 -0000 1.1872 +++ ChangeLog 6 Aug 2007 13:55:04 -0000 @@ -1,3 +1,7 @@ +2007-08-06 Simon Josefsson <[EMAIL PROTECTED]> + + * build-aux/maint.mk, build-aux/GNUmakefile: Relicense to GPLv3+. + 2007-07-31 Bruno Haible <[EMAIL PROTECTED]> * m4/stdint.m4 (gl_STDINT_H): Test whether WCHAR_MIN and WCHAR_MAX Index: build-aux/GNUmakefile =================================================================== RCS file: /sources/gnulib/gnulib/build-aux/GNUmakefile,v retrieving revision 1.2 diff -u -p -r1.2 GNUmakefile --- build-aux/GNUmakefile 14 Feb 2006 12:52:55 -0000 1.2 +++ build-aux/GNUmakefile 6 Aug 2007 13:55:04 -0000 @@ -4,21 +4,20 @@ # It is necessary if you want to build targets usually of interest # only to the maintainer. -# Copyright (C) 2001, 2003, 2006 Free Software Foundation, Inc. +# Copyright (C) 2001, 2003, 2006, 2007 Free Software Foundation, Inc. # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by -# the Free Software Foundation; either version 2 of the License, or -# (at your option) any later version. +# the Free Software Foundation; either version 3 of the License, +# or (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
