commit 3e80b12fde6126d85ae2ee58ba57e499c57b6c92 Author: Takashi Yano <[email protected]> Date: Tue Sep 14 12:48:03 2021 +0900 Cygwin: fhandler_base::dup Reflect O_CLOEXEC to inheritance flag. - Currently fhandler_base::dup duplicates handles with bInheritHandle TRUE unconditionally. This patch reflects O_CLOEXEC flag to that parameter.
