Hi
I completed execution of all tests and added the
dg-require-normal-namespace to a few more files.
I also eventually prefer to keep dg-require-normal-mode and
dg-require-normal-namespace seperated, the first for alternative modes,
the latter for versioned namespace.
With this patch there is no more conformance tests failing with
versioned namespace.
Ok to commit ?

Hi
I would like to propose to add a new dg-require-normal-namespace
attribute to make several tests failing when version namespace is
active UNSUPPORTED. It is like dg-require-normal-mode but also
consider when version namespace is being used.
I still need to complete execution of all tests with version
namespace but I think that all tests will be ok then.
I have also updated the code used for dg-require-normal-mode to
include c++config.h in case users are changing this file to activate
any mode.
* testsuite/lib/libstdc++.exp
([check_v3_target_normal_namespace]): New.
* testsuite/lib/dg-options.exp ([dg-require-normal-namespace]): New,
use latter.
* testsuite/23_containers/headers/bitset/synopsis.cc: Replace
dg-require-normal-mode with latter.
