From 081d682b263decd8d4b60a8351de30c0e563f751 Mon Sep 17 00:00:00 2001 From: "Anthony G. Basile" Date: Fri, 23 Nov 2012 08:55:12 -0500 Subject: Remove undeeded macros from m4 directory The acx_libwrap.m4 and attributes.m4 were used for checks related to libwrap and compile attribute/flags, respectively. Since these have been removed from the build system, they are left over lint. Files can be retrieved by git checkout ddfb9b07df -- Signed-off-by: Anthony G.
