C++ language issues

Header dependency changes

+

Some C++ Standard Library headers have been changed to no longer include +other headers that were being used internally by the library. +As such, C++ programs that used standard library components without +including the right headers will no longer compile. +

+

+The following headers are used less widely in libstdc++ and may need to +be included explicitly when compiled with GCC 13: +
