The only thing I find in ChangeLog.2 relating to this is,

Tue Aug 27 13:12:21 1996  Jason Merrill  <jason@yorick.cygnus.com>
        
        * call.c (add_builtin_candidate): Use TYPE_PTROB_P instead of
        ptr_complete_ob.
        (joust): If we're comparing a function to a builtin and the worst
        conversion for the builtin is worse than the worst conversion for the
        function, take the function.
I can't tie this up to a test case.
ring any bells?
