Yes but you are using the extension incorrectly anyways as you don't pass this
to the function.  Did you read that page?

     extern A a;
     extern int (A::*fp)();
     typedef int (*fptr)(A *);

     fptr p = (fptr)(a.*fp);

While you do:
        pf f1 = (pf)( o->*pmf );
        f1();

Really it should have been:
f1(o);
