gcc 4.8: broken headers when using gnu-versioned-namespace

[Oleg Smolsky]

Hey all, I've just built gcc 4.8 with 
--enable-symvers=gnu-versioned-namespace and compilation of a small test 
fails with the following:

In file included from /work/opt/gcc-4.8/include/c++/4.8.0/array:324:0,
                  from /work/opt/gcc-4.8/include/c++/4.8.0/tuple:39,
                  from 
/work/opt/gcc-4.8/include/c++/4.8.0/bits/stl_map.h:63,
                  from /work/opt/gcc-4.8/include/c++/4.8.0/map:61,
                  from ....................
/work/opt/gcc-4.8/include/c++/4.8.0/debug/array:296:12: error: 
‘tuple_size’ is not a class template
      struct tuple_size<__debug::array<_Tp, _Nm>>
...
...

It looks like include/c++/4.8.0/debug/array is missing a couple of wrappers:

_GLIBCXX_BEGIN_NAMESPACE_VERSION
_GLIBCXX_END_NAMESPACE_VERSION

IE it is a similar thing to this change:
     http://gcc.gnu.org/viewcvs/gcc?view=revision&revision=193584

Should I re-open the bug?

Oleg.
