--- Comment #9 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Simplified:

template<template<class, class> class>
class basic_json;

template<class> struct json_pointer {
  template<template<class, class> class> friend class basic_json;
};

template struct json_pointer<int>;
template struct json_pointer<char>;
template struct json_pointer<long>;
