Oops, sorry! I've committed the attached patch to remove the const.

        * object.h (Object::get_output_view): remove const from return type.
        (Object::do_get_output_view): Likewise.
        (Sized_relobj_file::do_get_output_view): Likewise.
        * reloc.cc (Sized_relobj_file::do_get_output_view): Likewise.

Yes, we have a few other similar casts. It's not a high priority, but
I'll eventually see about adding a virtual function to the Object
class to return a Sized_relobj_file pointer to itself.

No problem; let me know when it's ready.
