are you sure? For foo(1) a temporary Dummy object must be created

IMHO this is braindead and other compiler can handle it. And as you 

"The constructor that would be used to make the copy shall be callable 
whether or not the copy is actually done"

the standard uses the word "shall" and not "must". So GCC 3.4.0 should 
not treat this as an error (only if GCC really copies the temporary).
