Extensions for C++11 compatibility

Note:

Start of changeIBM® supports selected features of C++11, known as C++0x before its ratification. IBM will continue to develop and implement the features of the new standard. The implementation of the language level is based on IBM's interpretation of this standard. Until IBM's implementation of all the C++11 features are complete, including the support of a new C++11 standard library, the implementation may change from release to release. IBM makes no attempt to maintain compatibility, in source, binary, or listings and other compiler interfaces, with earlier releases of IBM's implementation of the new C++11 features and therefore they should not be relied on as a stable programming interface.End of change

Start of changeThe following features are part of a continual phased release process leading towards full compliance with C++11. They can be enabled by the LANGLVL(*EXTENDED0X) option. End of change
