Thanks.

Unfortunately it breaks the following testcase:

 ~ % cat asm-js.ii
struct A {
  void operator delete(void *, unsigned long);
};
struct B : A {
  virtual ~B();
};
struct C : B {};

 ~ % g++ -c asm-js.ii
asm-js.ii:7:8: error: no matching function for call to ‘C::operator 
delete(void*)’
 struct C : B {};
        ^
asm-js.ii:2:8: note: candidate: ‘static void A::operator delete(void*, long 
unsigned int)’
   void operator delete(void *, unsigned long);
        ^~~~~~~~
asm-js.ii:2:8: note:   candidate expects 2 arguments, 1 provided
