Subject: [PATCH] checksyscalls: ignore -Wunused-macros
Date: Sat, 23 Apr 2022 00:17:25 +0900	[thread overview]
Message-ID: <20220422151725.1336997-1-mailhol.vincent@wanadoo.fr> (raw)

The macros defined in this file are for testing only and are purposely
not used. When compiled with W=2, both gcc and clang yield some
-Wunused-macros warnings. Ignore them.
