I think it's all right to be conservative here.  The inference rules could get quite complicated if (for example) the use looked like this

  extern void foo (double *bar);
  extern __unknown_anytype func();
  // ...
  foo(&func());

One could come up with even more complicated cases.  It's probably not worth making sure they all work.
