If you should really plan to do this, please add a new PyLong_AsString()
API, so that extensions can query the long int value using the
string format (probably the most portable way of passing long int
values from one implementation to another). A PyLong_FromString() API
would be a nice complement to PyLong_AsString()... it could use the
code from the builtin long() as engine.

I'm currently using PyObject_Str() on Python long integers to
have converted to strings and chop off the trailing 'L' "by hand".
Not really very elegant, but it works :-)
