call of overloaded ... is ambiguous


c++primerに書いた関数テンプレートの例に従って

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;
}


次のエラーが発生しました.

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]

mingw32/3.4.2/../../../../include/c++/3.4.2/bits/stl_algobase.h:151:

[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/

なぜならstdには既にminという名前の関数(stl_algobase.hファイルの148行)があり、名前の競合が発生しているためです.
