Visual Studio 2010 Express does not compile googletest due to tuple issue about googletest HOT 3 CLOSED

We will track it in the issue 217. A workaround is suggested there.

A simple temporary solution to make his/her code to compile is to move the
tuple_element structure to the gtest_internal namespace as it is incompatible 
with
the other definition in MSVC tuple header.

I fixed it by changing in gtest-tuple.h (line 741):

//--------------------------
template <int k, class Tuple>
struct tuple_element {
  typedef typename gtest_internal::TupleElement<
      k < (tuple_size<Tuple>::value), k, Tuple>::type type;
};

#define GTEST_TUPLE_ELEMENT_(k, Tuple) typename tuple_element<k, Tuple >::type
//--------------------------

 to 

//--------------------------
namespace gtest_internal {

template <int k, class Tuple>
struct tuple_element {
  typedef typename TupleElement<
      k < (tuple_size<Tuple>::value), k, Tuple>::type type;
};

} //namespace gtest_internal

#define GTEST_TUPLE_ELEMENT_(k, Tuple) typename gtest_internal::tuple_element<k,
Tuple >::type
//--------------------------

this is a dup of issue 217, which is fixed in the 
trunk.
