请教：函数二义性问题，谢谢

fanzhijie875151

下面是Linux下一段代码，报出错误：call of overloaded 'swap(int &, int&)' is ambiguous 等等
同样我把代码写在VC++6.0上也报出错误：ambiguous call to overloaded function
希望大家帮我看下，如何解决呢，谢谢大家。
code in VC++6.0 (在Linux下头文件需要指明路径)：

#include <iostream>

template <class Any>
void swap(Any &a, Any &b);

int main()
{
    using namespace std;
    int i= 10;
    int j= 20;
    cout << "Using complier-generatd int swapper.\n";
    swap(i, j);
    cout << "i, j = " << i << ", " << j << ".\n";

    double x= 24.5;
    double y= 81.7;
    cout << "Using complier-generatd double swapper.\n";
    swap(x, y);
    cout << "x, y = " << x << ", " << y << ".\n";

    return 0;
}

template <class Any>
void swap(Any &a, Any &b)
{
    Any temp;
    temp= a;
    a= b;
    b= temp;
}

STL 裏面已經有這樣的一個 swap 了，你再定義一個，compiler 當然不知道該用哪個好，用 g++ 的話可參看 /usr/include/c++/4.2/bits/stl_algobase.h
