gccxml is just dumping what gcc's parser produces.  The parser seems to
be producing the declarations for these operators but until they are
required does not try to compile them.  The compiler itself does not
distinguish them until code tries to do an assignment.

I've come up with a hack that pretends these artifical methods are
called, suppresses any resulting error messages, and then discards the
methods if errors occurred.  It seems to work for the examples you provided.
