handling of pointer to memberfunction

Hi everybody,

for function overloading, a pointer to a memberfunctionpointer is
considered to be of the same type as a const pointer to a
memberfunctionpointer. (I know, too may pointers :-)

I found this weird behaviour when I tried to instantiate a stl vector
of pointers to memberfunctions. The error happened in the allocator

The simple test program which I've attached shows the problem.
