From: Thomas Weißschuh Date: Wed, 18 Mar 2026 16:12:43 +0000 (+0100) Subject: selftests/nolibc: enable -Wundef X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c8f6a4bbad3b1a96572d1ac1d5c37bae109fa664;p=thirdparty%2Fkernel%2Flinux.git selftests/nolibc: enable -Wundef 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.
