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)
