--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-05-12 21:37:08 UTC --- The current plan according to Frédéric is to defer it until Bugzilla 4.2, which should allow this feature without hacks - rather than introducing further hacks. (See attachments to PR 43011 for the currently required patches.)
