Hello,
=20
we would like to use Cygwin. After checking the license conditions we found=
 two license conflicts in Cygwin, which is GPL v2 licensed in accordance wi=
th the COPYING files of Cygwin:
=20

The following files are GPL v3 licensed:

2) GPL v2 - BSD with Advertising Clause incompatibility: (see http://www.gn=
u.org/licenses/license-list.html section Original BSD License)
=20
The following files are BSD (with Advertising Clause) licensed
\cygwin-1.7.1-1\winsup\cygserver\sysv_shm.cc
\cygwin-1.7.1-1\winsup\testsuite\winsup.api\shmtest.c
\cygwin-1.7.1-1\winsup\testsuite\winsup.api\semtest.c
\cygwin-1.7.1-1\winsup\testsuite\winsup.api\msgtest.c
=20

In order to solve the GPL v2 - GPL v3 conflict, the GPL v2 license could be=
 changend in a "GPL v2 or later" license.
Another solution would be to change the license of the GPL v3 licensed file=
s into the GPL v2 license.
=20
A solution of the GPL v2 - BSD with Advertising Clause conflict could be to=
 remove the advertising clause in the BSD license.
=20
Is it possible for you to do such license changes, so that we can use Cygwi=
n?
=20
Thank you in advance!
