From c8f6a4bbad3b1a96572d1ac1d5c37bae109fa664 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Thomas=20Wei=C3=9Fschuh?= Date: Wed, 18 Mar 2026 17:12:43 +0100 Subject: [PATCH] selftests/nolibc: enable -Wundef MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Users might use -Wundef, so also use it in the nolibc testsuite to ensure no warnings are triggered. The existing line with warning options is getting too long, so move all warnings to a dedicated line.
