From 2a2a6486a089b90d05b258bd853d136f00cb7c69 Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Wed, 14 Feb 2024 14:00:34 +0100 Subject: [PATCH] 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.
