The reason is because at the time of the declaration of A::A(ft), the
class A is incomplete; you can see this if you were to attempt declare the
member function as 

    A(ft f = &A::F1): pf(f) { }

which is the more complete form -- you'll get the error "incomplete type
`A' does not have member `F1'."  Unfortunately, you're forced to use your
second case or the equivalent.
