Is there a mechanism for suggesting a package to be added toports?

Anders,

thanks for testing :-)

AFAIK partial member spezialization on the return value of a method is
not supported with g++ 2.95.

Example (from synopsis-0.7/Cxx-API/include/Synopsis/Python/Object.hh)

// ...

class Object
{

// ...

public:
// ...

 //. try to downcast to T, throw on failure
  template <typename T>
  static T narrow(Object) throw(TypeError);

// ...

};

template <typename T>
inline T Object::narrow(Object o) throw(Object::TypeError)
{
  T retn(o.my_impl);
  Py_INCREF(o.my_impl);
  return retn;
}

// ...

template <typename T>
inline char Object::narrow(Object o) throw(Object::TypeError)
{
  if (!PyString_Check(o.my_impl) || PyString_GET_SIZE(o.my_impl) != 1)
    throw TypeError("object not a character");
  char *value;
  int length;
  PyString_AsStringAndSize(o.my_impl, &value, &length);
  return value[0];
}

// ...

So, I think the best is to make the port use gcc 3.3 on FreeBSD 4.x. Of
course it has to be checked whether synopsis compiled with gcc 3 works
with boehm-gc and python compiled with the system compiler (2.95.4).

I have uploaded an updated version of the port:
