Thanks! I tried this:

     class X {
         version(Windows) {
             pragma(mangle, X.call.mangleof.replace("QBV","PBV"))
             final void call(const(Y)) const;
         } else {
             final void call(const(Y)) const;
         }
     }

and it worked. Thanks very much again!
