Aha, that DR was reverted by http://wg21.link/lwg1522 (I failed to find it
because the deleted text says "All the specified ..." and I searched for "All
of the specified ..."

I think Marc's point is that GCC is doing what DR 1137 says ... but it looks as
though the DR resolution never made it into C++11.

I absolutely agree, that the definition of the std::conj() overloads in C++11
is problematic.  However, in my opinion one has to be strict when implementing
the standard.  Otherwise, people might accidentally write non-portable C++11
code and g++ does not complain.
