This problem still exists for 2.4.1 ... here is why

gtest-tuple.h line 741:
template
struct tuple_element {
  typedef typename gtest_internal::TupleElement<
      k < (tuple_size::value), k, Tuple>::type type;
};

The tuple_element in stl expects size_t as first parameter, and size_t for x64 
is a bit larger than size_t for Win32. Hence the error:

error C3855: 'std::tr1::tuple_element': template parameter '_Idx' is 
incompatible with the declaration

So the correct code for this should look like this:

gtest-tuple.h line 741:
template <size_t k, class Tuple>
struct tuple_element {
  typedef typename gtest_internal::TupleElement<
      k < (tuple_size::value), k, Tuple>::type type;
};
