I see. Given

struct s{
  struct m{};
  template<class T>
  void m(struct m){}
};

int main()
{
  s x;
  struct s::m M;
  x.template m<int>(M);
}

the current g++ emits (under new ABI) _ZN1s1mIiEEvNS_1mE, which is
'void s::m<int>(s::m)'. Based on your description, I'd say that ::s::m
is a substitution candidate, so it should be '_ZN1s1mIiEEvS0', right?

I'm not sure what would need to be changed here: the spec or
g++. However, I do feel that there is need for action.
