[Bug c++/28370] [4.2 Regression] undefined reference to template class static variable in an anonymous namespace

["pinskia at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #8 from pinskia at gcc dot gnu dot org  2006-07-13 14:08 -------
Here is a full reduced self contained testcase:
namespace 
{
    template< typename Inst>
    struct rtl_Instance
{
    static int * m_pInstance;
};

template< typename Inst> int * rtl_Instance< Inst>::m_pInstance = 0;
}

int *foo(void)
{
    return rtl_Instance<int >::m_pInstance;
}
int main (void)
{
    return foo() == 0;
}
--------------------
It is only happens the namespace is anonymous which is why this is 4.2 only
regression.  Jason also applied his patch to redhat's 4.1 branch.

Caolan, please next time test against a FSF release of the compiler before
filing a bug because sometimes redhat backports patches to their branch.
