Any reason not to show the list of candidates, as you do when it is the function rather than the argument that is overloaded? That would help the user IMO. Often it's quite hard to find all the overloads on e.g. library functions. I have frequently resorted to making a bogus call on a function just to get a list.

Actually that is true, the error message has not changed since at least 3.0, before in 2.95.3 we used 
{unknown type} instead of <unknown type> but really the error message has not changed at all.

Indeed.  The systematic use of unknown_type_node for the type
of overload-set is recent -- it has been systematic with the
new parser.

We've been there before. You get these error messages for cases like 
this: 
-------------- 
int f(); 
int f(int); 
 
int g(int); 
int g(double); 
 
int i = g (&f); 
--------------- 
g/x> /home/bangerth/bin/gcc-3.5-pre/bin/c++ -c x.cc 
x.cc:7: error: no matching function for call to `g(<unknown type>)' 
x.cc:4: note: candidates are: int g(int) 
x.cc:5: note:                 int g(double) 
 
I concede that the error message could be improved by using something 
like 
  <set of overloaded functions> 
instead of 
  <unknown type>
