--- Comment #17 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-07-03 08:34:51 UTC --- (In reply to comment #15) > Also, didn't this already make it into the 4.7 release? Wouldn't reverting it > now just cause incompatibilities with 4.7 and both older and newer releases? Yes. But 4.7.0 and 4.7.1 are already incompatible with older releases. The maintainers have taken the decision to restore compatibility with older releases. We plan to try and reimplement the change in a cleaner way asap.
