[Bug c++/20484] New: No proper linkage created for in class initialized static const

["dopheide at fmf dot nl" <gcc-bugzilla at gcc dot gnu dot org>]

Example:
template <typename T>
T const max1(T const a, T const b)
{ return a < b ? b : a; }

template <typename T>
T const & max2(T const & a, T const & b)
{ return a < b ? b : a; }

struct Test
{ static int const A = 1; };

int main()
{
#if 0
  max1(Test::A, 2);     // OK.
#else
  max2(Test::A, 2);     // Does not link: undefined reference to `Test::A
#endif
}

The problem does not appear in 2.95.4
The problem does appear in 3.0.4, 3.2.3
Also appeared on 3.4.4 x86_64
