tuple_cat gives errors with nvcc

double_pack.cu

// This Compiles

#include <tuple>

template <typename ...T>
struct A {
    template <typename ...U>
    std::tuple<T..., U...>
    make(T... x, U... y) {
        return std::tuple<T..., U...>(x..., y...);
    }
};

int main() {
    A<int, char> x;

    x.make(3, '3', 5.6, 4.f);
}

tuple_cat.cpp

#include <tuple>

template <typename ...T>
struct A {
    std::tuple<T...> x;

    A(T... v) : x(v...) {}
};

template <typename ...T>
std::tuple<T...> transform(A<T...> a) {
    return a.x;
}

template <typename T>
std::tuple<T> transform(T x) {
    return std::tuple<T>(x);
}

template <typename ...Tuples>
auto cat(Tuples && ...tuples) -> decltype(std::tuple_cat(transform(tuples)...))
{
    return std::tuple_cat(transform(tuples)...);
}

int main() {

    A<int, char, float> x(3,'c',4.5f);

    cat(5, x, 6.7);

}

tuple_cat.cu

#include "./tuple_cat.cpp"

for the record:
this is the minimal setup to reproduce the issue

#include <tuple>
int main() {
  auto x = std::make_tuple(42);
  std::tuple_cat(x, x, x);
}

boost configuration code explicitly disables the usage of variadics if the cuda version is < 7.5 or is between 8.0 and 8.1 (I wonder what 8.1 is?)
and there is link in the comments explaining why: https://svn.boost.org/trac10/ticket/11897
I am not sure if it is the same issue as in our case though.
This issue is not reproduced on my mac laptop with the same cuda version as on daint and the clang version 3.8. It looks like tuple_cat is implemented differently here.
