从KlayGE 4.2开始，一些C++11特性被引入代码中，部分替代了原先使用boost实现的功能。包括：

C++11核心语言功能

  • Static assertions
  • auto-typed variables
  • Declared type of an expression
  • Null pointer constant
  • Strongly-typed enums
  • Range-based for
  • Rvalue references

C++11核心语言功能：并行

C++11核心语言功能：C99

  • long long

C++11库

  • Array
  • Chrono
  • Functional
  • Integer
  • Random
  • Regex
  • System
  • Thread
  • Tuple
  • Type Traits
  • Unordered

各编译器启用的功能对比

根据编译器和版本的不同，KlayGE会定义一些宏，来判断一个功能是否可用。这些宏定义在KFL/Config.hpp中。
