This is mistaken.  The IA-64 ABI requires that there must be only one 
function descriptor for a function, and thus comparing function pointers 
works even though they point at descriptors instead of functions.  This 
was pointed out at the conference.  Andreas was unfamiliar with this 
part of the IA-64 ABI.
