From 54751f4d33e6788392ac4637865efc216dec2774 Mon Sep 17 00:00:00 2001 From: Yang Tse Date: Fri, 29 Jun 2012 16:40:29 +0200 Subject: [PATCH] cares-compilers.m4: remove -Wstrict-aliasing=3 from clang Currently it is unknown if there is any version of clang that actually supports -Wstrict-aliasing. What is known is that there are several that don't support it. --- m4/cares-compilers.m4 | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/m4/cares-compilers.m4 b/m4/cares-compilers.m4 index d564792..8120aab 100644 --- a/m4/cares-compilers.m4 +++ b/m4/cares-compilers.m4 @@ -15,7 +15,7 @@ #*************************************************************************** # File version for 'aclocal' use.
