在VS2010中调用Winsock（winsock or winsock2）的bind函数时很有可能会出现一些莫名其妙的错误而导致编译失败，控制台输出的错误信息指向了库中的xxresult，和程序本身的设计似乎没有任何关联。
控制台片段：
1>c:\\program files\\microsoft visual studio 10.0\\vc\\include\\xxresult(28): error C2825: '_Fty': must be a class or namespace when followed by '::'
1> c:\\program files\\microsoft visual studio 10.0\\vc\\include\\xxresult(40) : see reference to class template instantiation 'std::tr1::_Result_type2<__formal,_Fty,_Arg0,_Arg1>' being compiled
1> with
1> [
1> __formal=false,
1> _Fty=__w64 unsigned int,
1> _Arg0=std::tr1::_Nil &,
1> _Arg1=std::tr1::_Nil &
1> ]
1> c:\\program files\\microsoft visual studio 10.0\\vc\\include\\xxresult(597) : see reference to class template instantiation 'std::tr1::_Result_of2<_Fty,_Farg0,_Farg1>' being compiled


实际上这是由于在VS2010中Winsock的 bind()与TR1（C++ Technical Report 1）的bind() 冲突导致的。在VS2010中微软将TR1中的bind()声明在名称空间 std 中，而Winsock的bind() 则声明在全域（global namespace），当在代码中使用“using namespace std ”这样的语句引入整个名称空间后，由于此时存在两个bind()，且TR1的bind()是一个模板在编译器重载解析时具有较高的优先级，直接调用bind()将导致了TR1对Winsock调用的覆盖，接下来在编译阶段的类型错误就不足为怪了。
解决的方法很简单，只要让编译器能够正确区别两者就可以了。为了解决由于使用"using namespace std"带来的冲突，我们需要在全域调用时显式的声明，如 “::bind()” ，这样编译器就只会在全域中解析该函数的调用，而不会导致冲突。以后遇到类似的情况，都可以通过全域声明（::call()）来解决。

问题解决，结贴

Thanks for reporting this issue. I've resolved it as By Design because the libraries are behaving correctly. Winsock's bind() is declared in the global namespace. <functional>'s bind() is declared in namespace std (I am skipping over some subtleties that are not relevant here). They coexist happily despite having the same name, because that's what namespaces are for.

However, when you say "using namespace std;", you make all of the names in namespace std available to unqualified name lookup. Therefore, both Winsock's bind() and <functional>'s bind() are considered during overload resolution, and because <functional>'s bind() is a template, it will usually win, but fail to compile later. That's why the compiler error here is so horrible.

To fix this, call ::bind() when you want Winsock's bind(), and std::bind() if you ever want <functional>'s bind(). When you call ::bind(), you're asking the compiler to look in the global namespace only.

我也是

真的非常感谢楼主，我今天下午遇到一个问题，原来编译的时候没有问题，后来又新添加了一个hpp和cpp文件后就各种报错，说是xxresult里面的28行和40行有错误，我以为是我新添加的文件的问题，看了楼主的帖子后试着把bind()改成::bind()，问题就迎刃而解了，否则的话我都不知道怎么解决了，十分感谢楼主
