patch

Add USES=3Dcompiler:c++11-lang.

CXXFLAGS+=3D-Wno-error=3Dreturn-type is necessary to fix:

error: no return statement in function returning non-void [-Werror=3Dreturn=

e]
   Index set_restart(const Index restart) { m_restart=3Drestart; }

I added it only for GCC architectures.

Tested on powerpc64 and amd64.
