* Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen2016-06-231-3/+0
| | | | | | | | | | | | | | Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause. Everything else stays under GPLv3+. New Linking Exception exempts resulting executables from LGPLv3 section 4. Add CONTRIBUTORS file to keep track of licensing. Remove 'Copyright Red Hat Inc' comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Revert "Refactor to avoid nonnull checks on "this" pointer."Corinna Vinschen2016-04-051-8/+8
| | | | | | | | | This reverts commit 0008bdea02b690ab19ffe997499cb9a96ee5a66d. This patch introduced a regression. Calling FOO=$(...) in zsh hangs indefinitely and has to be killed forcefully. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
