commit 784ce7aff8c92b6b729e8bf5564e582360c24d8c Author: Corinna Vinschen <[email protected]> Date: Wed Feb 14 14:00:34 2024 +0100 Cygwin: accommodate gcc -Og option All three warnings produced with -Og are false positives. But given we're using -Werror unconditionally it's better to be safe than sorry.
