2021. Function template redeclaration via alias template

Section: 13.7.7.2  [temp.over.link]     Status: dup     Submitter: Richard Smith     Date: 2014-10-15

See also issue 2025.

Given the declarations

 template<int> using T = int; template<typename U> void h(T<f(U())>); template<typename U> void h(T<g(U())>);

Does this declare one function template or two?

Rationale (November, 2014):

This issue is a duplicate of issue 1980.
