From: Christophe Fergeau <cfergeau@xxxxxxxxxx> A missing AX_CXX_COMPILE_STDCXX_11 at autoreconf time will only trigger a non-fatal "command not found" when configure runs, but then compilation will unexpectedly fail unless -std=c++11 is added to the CXXFLAGS. This commit makes sure we error out at autoreconf time when the macro is unknown.
