Created attachment 317710 [details] Build log This is the build log, it's from my local overlay because I have to apply my patch from bug 425380 to build with automake 1.12
Created attachment 317712 [details, diff] Patch to compile with gcc 4.7 This is the debian patch from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=667378 I just cut out all the debian parts and made it into a normal patch, rather than a patch creating a patch.
Patch LGTM.
Applied in sphinx-2.0.4-r1
