Fixed in GCC 5.1.0:

d.cc:2:31: error: redeclaration of ‘template void f(int)’ may not have
default arguments [-fpermissive]
 template void f(int=3); // ill-formed
   ^

If we don't have one, we should add a testcase for this and close it.

We diagnose this if the function template is instantiated. I'm not sure if
we're required to diagnose it for uninstantiated templates.

Oops, I messed up my test - we don't diagnose this even at instantiation
