From cfe1fcb4eefba66243ecf1336e38f4e77a491cff Mon Sep 17 00:00:00 2001 From: Alan Coopersmith Date: Mon, 15 Jan 2024 11:44:21 -0800 Subject: [PATCH 04/15] Quiet -Wredundant-decls from xorg/os.h fallbacks for new libc functions The Xorg headers provide their own versions of strlcat, strlcpy, and timingsafe_memcmp for platforms that don't have them in libc yet, but rely on configure to set HAVE_* defines to determine if they should be defined in the headers.
