Subject: [PATCH] Cygwin: console: Fix yet another bug on input when signalled.
Date: Tue,  2 Nov 2021 17:09:40 +0900	[thread overview]
Message-ID: <> (raw)

- Currently, read() returns EINTR due to a bug if signal handler
  is SIG_DFL and the process is suspended by Ctrl-Z and restarted.
  This patch fixes the issue.
