Output of -v option

The following simple code compiling with -std=c++11 and -D_GLIBCXX_DEBUG is
rejected by GCC 4.9.0 20130331 configured with
--enable-symvers=gnu-versioned-namespace.

//--------------
#include <array>
//--------------

The issue is not reproduced when either
--enable-symvers=gnu-versioned-namespace (in GCC configure option) or
-D_GLIBCXX_DEBUG (in compile option) is unset.
