[pygccxml-development] Bug in virtual function wrapping with pyplusplus

[Allen B. <al...@vr...>]

I think I have found a bug in the handling of virtual methods with 
pyplusplus.

I have attached a set of test classes and the generated bindings.

The problem seems to be that when you have 3 classes derived from each 
other as:

class Grandpa
class Father : public Grandpa
class Son : public Father

And Grandpa declares a pure virtual method that is defined in Father but 
just used in Son, the wrapper for Son still thinks it is a pure virtual 
and doesn't know to generate code with the default implementation in 
Father.  (See the attached code, it really makes more sense with an example)
