call of overloaded ... is ambiguous

照着c++ primer上写的一个函数模板例子

using namespace std;

template <class T>
T min(T a, T b) {
	return a < b ? a : b;
}

int main() {
	cout<<min(10, 32)<<endl;
	cout<<min(24.1, 2.0)<<endl;
	return 0;
}

出现了如下错误:

function_template.cpp: In function `int main()':
function_template.cpp:11: error: call of overloaded `min(int, int)' is 

ambiguous
function_template.cpp:6: note: candidates are: T min(T, T) [with T = int]
D:/Program Files/mingw/MinGW/bin/../lib/gcc/
mingw32/3.4.2/../../../../include/c++/3.4.2/bits/stl_algobase.h:151:
note: const _Tp& std::min(const _Tp&, const _Tp&) 
[with _Tp = std::streamsize]

function_template.cpp:12: error: call of overloaded `min(double, double)' 

is ambiguous
function_template.cpp:6: note: candidates are: T min(T, T) [with T = 

double]
D:/Program Files/mingw/MinGW/bin/../lib/gcc/

note: const _Tp& std::min(const _Tp&, const _Tp&) [with _Tp = double]

原因是std中已经有了一个名字叫min的函数（在stl_algobase.h文件的148行），导致名字冲突，
