Check out compiler.m4:

         if test `uname` = "Darwin" ; then
           CXXFLAGS_DBG="$CXXFLAGS_DBG -std=c++0x -Woverloaded-virtual"
         else
           CXXFLAGS_DBG="$CXXFLAGS_DBG -std=c++0x -Woverloaded-virtual -D_GLIBCXX_DEBUG -D_GLIBCXX_DEBUG_PEDANTIC"
         fi

Are you not on a Darwin system?
