>Description:
The following snippet does not compile, although I believe
that it should. If instead of the constructor a regular
function is used, it works.

-----------------------------------------
template <int dim> struct T {};
struct X {
  template <int dim> X (T<dim> &) {};
};

template X::X<> (T<2> &);


-------------------------------------
x.cc:6: `X' is not a template
x.cc:6: ISO C++ forbids declaration of `type name' with no type
x.cc:6: abstract declarator `int (X::)(T<2>&)' used as declaration
x.cc:6: no member function `._0' declared in `X'
