tar 1.18 was just released, and is one of the first GNU packages that
requires GPLv3 or later. Meanwhile, cygwin is explicit in requiring
exactly GPLv2. According to the GPLv3 FAQ, http://gplv3.fsf.org/dd3-faq,
it is NOT okay for a GPLv3 program to link against a GPLv2-only library.
So, what is the consensus - am I allowed to upload tar 1.18, or is cygwin
forevermore stuck at tar 1.17 as the last GPLv2 release, because of the
fact that building an image of tar 1.18 linked against cygwin1.dll
constitutes a license violation?
And this problem will only grow in the near future - other cygwin packages
that I maintain have discussed in their mailing lists that they are
actively in the process of converting to GPLv3, including findutils
(release expected tomorrow) and m4 (release expected later in the week).

Remember that the Cygwin license includes an OSI exemption, so as long
as GPLv3 is eventually OSI certified (as if...) it's fine on the Cygwin
side. I don't know about the other direction though.

Thanks for the reminder about the exception clause. Since packaging tar
1.18 does not modify the sources to cygwin1.dll, I agree that the GPLv2
exception offered by cygwin is applicable here. I don't think GPLv3 will
have any problem achieving OSI exemption, so I went ahead and uploaded tar
1.18.
