commit caa78917b68a9f5cff65b22e0e53ebd53b2dc5c7 Author: Corinna Vinschen <[email protected]> Date: Tue Apr 6 21:26:33 2021 +0200 Cygwin: select: don't set ready for exception on socket shutdown So far select wrongly sets the descriptor as ready for exception when a shutdown occurs. This is entirely non-standard. Only set this bit on an out-of-band event.
