well I looked at the one referred to by the SF page at

        http://fixedpoint.sourceforge.net/TimsMessage.txt

ie
        http://starship.python.net/crew/aahz/FixedPoint.py

and it seems quite a number of changes were made since then. In
particular _mkFP is passed the constructor attributes rather than a
class constructor.

Starting with the SF one I replaced the usage of type(self) referring to
the current instance class with self.__class__ and that seems to
work.....,

but I'm not sure if type(instance) is exactly equivalent to
instance.__class__ in 2.2 so could be missing something.
