struct node { int* operator int*(); };
gets you:
foo.cc:1: error: operator `int*' declared to return `int'
BTW, a better diagnostic would be something like:
error: operator `int*' should not declare a return type

FWIW, here's the icc output:
tmp/g> icc -Xc -ansi -c x.cc
x.cc(1): error: return type may not be specified on a conversion function
struct node { int* operator int*(); };

I think this happens because when the C++ front-end finds that a
declaration is erroneous, it sets its TREE_TYPE to "int", presumably
thinking that a default type should be "int".

Gabriel: no, it also happens with any pointer:
struct node { float* operator float*(); };
gets you:
foo.cc:1: error: operator `float*' declared to return `float'
And similarly for other types including classes (not shown).
BTW, shouldn't the title be "diagnostic shows wrong type for conversion
function" ? I've never heard these called "cast operators".

Alright, that was a wrong guess.

------- Comment #6 from pcarlini at suse dot de 2007-08-06 11:52 -------
The subtle issue here is that this specific error message should be emitted
*only* when the incorrectly specified return type doesn't match, thus a plain
error instead of a pedwarn:
case sfk_conversion:
if (type && !same_type_p (type, optype))
error ("operator %qT declared to return %qT", optype, type);
else if (type)
pedwarn ("return type specified for %<operator %T%>", optype);
type = optype;
but for some reason the thing doesn't work... I'm looking a bit into it.
