From 2fd63590ae668fe70b04cfbf9ea8f5316a56bbda Mon Sep 17 00:00:00 2001 From: "Pedro F. Giffuni" Date: Sun, 28 Jan 2018 19:37:30 +0000 Subject: [PATCH] Avoid implicit gcc nonnull attribute in vwarnx(). We removed the nonnull attributes from our headers long ago, but still __printflike() includes it implicitly. This will cause the NULL check to be optimized away in higher -O levels and it will also trigger a -Wnonnull-compare warning. Avoid warning with it in vwarnx().
