 It's -W / -Wunused.  It looks like the generated copy constructor
 isn't getting DECL_ARTIFICIAL set properly.  It's being set in
 implicitly_declare_fn(), but the flag is no longer set when unused variables
 are checked.
 
 (I *think* that's the case.  Every time I try to investigate, gdb dumps
 core.)
