--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Phil Miller from comment #2) > Does the committee need another nudge on this point, as practice has shifted? I don't believe practice has shifted. The difference in GCC's behaviour is probably just a bug related to friend functions not a different interpretation of ADL for fundamental types.
