As distributed with GNU Emacs, the files is_exec.c and sigaction.c are

-- COPYING.DJ ENDS HERE --
|
||
|
||
Both is_exec.c and sigaction.c are parts of DJGPP's libc.a, therefore
|
||
according to exception 1 in the above terms their "base" license is
|
||
the GNU Library General Public License [now known as the GNU Lesser
|
||
General Public License].
|
||
|
||
The terms of the GNU LGPL, specifically clause 3, which begins:
|
||
|
||
3. You may opt to apply the terms of the ordinary GNU General
|
||
Public License instead of this License to a given copy of the
|
||
Library.
|
||
|
||
permit us to relicense the files is_exec.c and sigaction.c as used in
|
||
GNU Emacs under the terms of the GNU GPL.
|
||
|
||
COPYING.DJ, however, lists extra exceptions 2-4 to the GNU licenses.
|
||
Items 3 and 4 are not relevant in the case of GNU Emacs, since they
|
||
can only apply to copies of DJGPP [confirmed by email from DJ Delorie
|
||
to rms at gnu.org and others, 2007/01/31].
|
||
|
||
Exception 2 of COPYING.DJ, when viewed as an added restriction, rather
|
||
than as an interpretation of the GPL, leads to problems. The added
|
||
requirement makes the overall license of the file incompatible with
|
||
the GNU GPL.
|
||
|
||
As a solution to this problem, DJ Delorie has kindly granted (February
|
||
2007) GNU Emacs an exception, and permits us to license the files
|
||
is_exec.c and sigaction.c solely under the terms of the GNU GPL. This
|
||
exception applies _only_ to these files as distributed with GNU Emacs.
|
||
This solution was arrived at in an email discussion between DJ Delorie
|
||
<dj at delorie.com> and Richard Stallman <rms at gnu.org> in
|
||
January/February 2007. We record below a summary of the relevant final
|
||
email in this discussion:
|
||
|
||
From: DJ Delorie <dj at delorie.com>
|
||
To: rms at gnu.org
|
||
Subject: Re: COPYING.DJ and Emacsn
|
||
|
||
I have no problem with whatever you wish to do with those files in
|
||
emacs (as long as djgpp itself doesn't need to change).
|
||
|
||
|
||
Accordingly, in February 2007 we relicensed the files is_exec.c and
|
||
sigaction.c as used in GNU Emacs under the GNU GPL.
|
||
