The patch did not fix the issue for me, unfortunately, because CXX_FOR_BUILD is still set to 'g++'. But to make it work, I added the line: CXX="$CXX -std=c++11", as shown in the file I have attached. With this additional line in both configure and configure.ac, CXX_FOR_BUILD is set to 'g++ -std=c++11', and the build succeeded for me. However, I do not know whether that is the right solution.
