commit 0a67adb0f518b1590bd94cdf98bed60888156bed Author: Takashi Yano <[email protected]> Date: Mon Apr 18 20:07:48 2022 +0900 Cygwin: pty: Fix Ctrl-C behaviour in latest GDB. - In the latest GDB (11.2-1), Ctrl-C behaviour is broken a bit for non-cygwin inferior. For example, Ctrl-C on GDB prompt is not sent to GDB but to the inferior. This patch fixes the issue.
