[Mingw-users] MinGW - Variadic Templates - no matching function for call.

[<mb...@mt...>]

I  am attemting to compile the code below, using MinGW on windows, as
below:
g++ -std=c++0x -Wall -Os -o varTest varTest.cpp

I receive the following compilation error:

I am more concerned about the potion below:

Why am I getting this error? (Source code is below).

#include <iostream>

	}

	auto sum(const T1& t1, const T2& t2, const T3&... t3)->decltype(t1 +
sum(t2, t3...)){

		return (t1 + sum(t2, t3...));

	}

	auto minus(const T1& t1, const T2& t2)->decltype(t1-t2){
