This patch introduced a regression in
20_util/tuple/creation_functions/tuple_cat.cc in debug mode.

Attached is a proposal to fix it properly. I am using <utility> as a
pivot header between <tuple> and <array>. This way <tuple> do not need
to include <array> anymore.

It also adds missing version namespace macro in debug and profile headers.

Not tested yet as I would like to know first if it ok to do it this way.
