Starting from KlayGE 4.2, some C++11 features are introduced to replace some features from Boost. KFL defines some macros based on compiler names and versions, to ensure which features are useable. Those macros are defined in KFL/Config.hpp.

Macros marked as italic is removed because all supported compilers have those features.
