commit 41ae84e6dcd810b9c94f1bbd5e00e6c8a28ccb94 Author: Ken Brown <[email protected]> Date: Thu May 28 13:05:32 2020 -0400 Cygwin: stat: fix st_mode of fifos again This partially reverts commit f36262d56ac78f04de147746ce4a85c6155e4a23. That commit incorrectly made the st_mode of a fifo reflect the Windows permissions of the disk file underlying the fifo.
