From 1132e1e448ce51e3b51fc7afdf661633abc4f202 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Sat, 15 Apr 2017 11:45:20 -0700 Subject: gcc-plugins: Detail c-common.h location for GCC 4.6 The c-common.h file moved in stock gcc 4.7, not gcc 4.6. However, most people building plugins with gcc 4.6 are using the Debian or Ubuntu version, which includes a patch to move the headers to the 4.7 location. In case anyone trips over this with a stock gcc 4.6, add a pointer to the patch used by Debian/Ubuntu.
