[PyKDE] function overload with different type using SIP

[Zilin Du]

Hi, I got some problem for using overload functions using SIP (4.3.2), 
here is my example:

class A {
public:
  A(long)
  A(unsigned long)
  A(double) 
  int cmp(long)
  int cmp(unsigned long)
  int cmp(double)   
};

when I run sip, sip complains:

A constructor with the same Python signature has already been defined
A function with the same Python signature has already been defined

if I remove:
  A(double)
  int cmp(double)
then no error.

so I don't know how we can define two overloaded function which can 
take long or double. Can anyone can share me his experience using sip?

Thanks!
