From b8103112ea8d9d03647a60f45768494dc14eaa1b Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 23 Mar 2013 22:26:29 +0000 Subject: [PATCH] gcc: add support for gcc 4.8 This commit adds support for the recently released gcc 4.8. We re-add the same patch series as the one used for 4.7.x, after refreshing the patches.
