I'm trying to be explicit about licensing in csih for the next release. 
I realize it's a little silly to use the GPL on a script (binary == 
source, right?), but it may be necessary because part of it is derived 
from cygport, which is GPLv3.

csih (the script part) has been derived from a number of sources:

#   ssh-host-config Copyright 2000, 2001, 2002, 2003 Red Hat Inc.
#     part of the Cygwin port of OpenSSH
(no explicit licensing)

#   cygport         Copyright (C) 2006, 2007 Yaakov Selkowitz
#     GPL v3
(mostly the messaging functions: csih_inform, csih_error, etc)

#   exim-config     Copyright Pierre A. Humblet, 2003-2007.
#   cron-config     Copyright Pierre A. Humblet, 2003-2007.
(no explicit licensing)

For the csih.sh function library, I'd like to use one of the following 
two licenses:

(1) MIT/X

or

(2) GPLv3 with an exception clause modeled after the javascript example 
from http://www.gnu.org/licenses/gpl-faq.html#WMS. See below.

In both cases, I need permission from the maintainers of the four 
packages above. With respect to csih.sh, I'd prefer MIT/X because (a) 
source == binary, so forcing "make sure the source is available" seems a 
bit silly, and (b) just less hassle all around.

In either case, the intent is so that the various foo-config scripts 
don't have to be as concerned about their own license terms, as long as 
they are just using csih.  Of course, if you copy the code for 
csih_foo() so that you can make a modified version of that function, 
then the full terms -- GPLv3 "viralness and all" if option #2, or no 
real impact if option #1 -- apply.

========= snap ==========

Can I get a yes or no from the three maintainers of all four of the 
packages listed below, on the following questions:

openssh
cygport
exim, cron

Can I use the MIT/X license for the portions of 
cygwin-service-installation-helper.sh that were derived from the config 
script(s) under your control?

Can I use the GPLv3-with-exception license above for the portions of 
cygwin-service-installation-helper.sh that were derived from the config 
script(s) under your control?

If both, which do you prefer?
