The <valarray> header in libstdc++ now includes <bits/ranges_access.h> when compiling for C++11 or later. This change enables the use of range-based for loops and the std::begin and std::end functions with std::valarray. This brings std::valarray in line with other container-like types that have been updated to support range access as a defect report against C++11.
