  27. //  本配置文件功能表:  
  28. //  (1)  如果不编译器没有定义bool, true, false则定义  
  29. //  (2)  如果编译器不支持drand48()函数则定义__STL_NO_DRAND48  
  30. //       注: drand48产生双精度的伪随机数, 因为采用了48bit计算, 故名drand48  
  31. //  (3)  如果编译器不支持static members of template classes(模板类静态成员),  
  32. //       则定义__STL_STATIC_TEMPLATE_MEMBER_BUG  
  33. //  (4)  如果编译器不支持'typename'关键字, 则将'typename'定义为空(null macro)  
  34. //  (5)  如果编译器支持partial specialization of class templates(模板类偏特化),  
  35. //       则定义__STL_CLASS_PARTIAL_SPECIALIZATION  
  36. //       参考文献: http://msdn.microsoft.com/en-us/library/9w7t3kf1(v=VS.71).aspx  
  37. //  (6)  如果编译器支持partial ordering of function templates(模板函数特化优先级),  
  38. //       则定义__STL_FUNCTION_TMPL_PARTIAL_ORDER  
  39. //       参考资料: http://msdn.microsoft.com/zh-cn/library/zaycz069.aspx  
  40. //  (7)  如果编译器支持calling a function template by providing its template  
  41. //       arguments explicitly(显式指定调用模板函数的模板参数)  
  42. //       则定义__STL_EXPLICIT_FUNCTION_TMPL_ARGS  
  43. //  (8)  如果编译器支持template members of classes(类模板成员),  
  44. //       则定义__STL_MEMBER_TEMPLATES  
  45. //  (9)  如果编译器不支持'explicit'关键字, 则将'explicit'定义为空(null macro)  
  46. //  (10) 如果编译器不能根据前一个模板参数设定后面的默认模板参数,  
  47. //       则定义__STL_LIMITED_DEFAULT_TEMPLATES  
  48. //  (11) 如果编译器处理模板函数的non-type模板参数类型推断有困难,  
  49. //       则定义__STL_NON_TYPE_TMPL_PARAM_BUG  
  50. //  (12) 如果编译器不支持迭代器使用'->'操作符,  
  51. //       则定义__SGI_STL_NO_ARROW_OPERATOR  
  52. //  (13) 如果编译器(在当前编译模式下)支持异常,  
  53. //       则定义__STL_USE_EXCEPTIONS  
  54. //  (14) 如果我们将STL放进命名空间中,  
  55. //       则定义__STL_USE_NAMESPACES  
  56. //  (15) 如果本STL在SGI的编译器上编译, 并且用户没有选择pthreads或者no threads,  
  57. //       则默认使用__STL_SGI_THREADS  
  58. //       注: POSIX thread 简称为pthread, Posix线程是一个POSIX标准线程.  
  59. //  (16) 如果本STL在Win32平台的编译器上使用多线程模式编译,  
  60. //       则定义__STL_WIN32THREADS  
  61. //  (17) 适当的定义命名空间相关的宏(__STD, __STL_BEGIN_NAMESPACE, 等)  
  62. //  (18) 适当的定义异常相关的宏(__STL_TRY, __STL_UNWIND, 等)  
  63. //  (19) 根据是否定义__STL_ASSERTIONS, 将__stl_assert定义为断言或者空(null macro)
