[Bug c++/19966] New: Misleading message "must take exactly one argument"

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following invalid code snippet causes a bogus error message:

==============================
struct A
{
    static operator int();
};
==============================

bug.cc:3: error: 'static A::operator int()' must be a nonstatic member function
bug.cc:3: error: 'static A::operator int()' must take exactly one argument

The first part is ok, but the second part is bogus, as the operator
(once made non-static) will take no argument. Well, the this-pointer
could be counted as an argument, but this is nevertheless confusing
for the user. Especially, since the second error message will indeed
go away if one adds a parameter.
