Strange problem with msvc in kdepimlibs/kcal

[Christian Ehrlicher]

Hi,

I want to compile kdepimlibs with msvc (because kdebase needs it) and after some minor problems I now get a strange error in kcal. I've attached a small testcase to show the problem.

The output with gcc:

D - Recurrence::Observer::Observer()
G - Incidence::Incidence()
A - RecurrenceRule::Observer::Observer()
E - Recurrence::Recurrence()
F - void Recurrence::addObserver(Recurrence::Observer*)

and msvc:

A - RecurrenceRule::Observer::Observer
G - Incidence::Incidence
A - RecurrenceRule::Observer::Observer
E - Recurrence::Recurrence
F - Recurrence::addObserver

As you can see, different constructors are called.
In my understanding, both of them are correct. But I don't know what the c++ standard says about such an ambiguity.

Any ideas how this could be solved without renaming one of the classes? 

Christian
