using <tuple> with ARMCC (ARMv5 toolchain)

Hi, 

I would like to work with GoogleTest to perform unit test. GTest use tuples and type_traits as I see #include <tuple> and #include <type_traits> in some files. When I compile, I have file not found errors. It works fine when using MSVC toolchain. I see that there is no tuple nor type_traits file in the Keilv5 lib folder as there is in MSVC/ folder for example.

Can you confirm that tuple and type_traits are not available for this toolchain? ARMv5 is supposed to handle C++11 and tuple was introduced with C++11.

What would be the alternative?

Thank you for your help
