Oops! You're quite right, pi is automatic in my test case. However compilation
still fails if pi is given internal linkage by declaring it static, i.e.

int main()
{
  static constexpr float pi = 3.14;

Or even:

namespace {
  static constexpr float pi = 3.14;
}
int main()
{

Can you provide an example of a variable with internal linkage being used as a
reference template parameter that compiles using g++?
