--- Comment #6 from Uros Bizjak <ubizjak at gmail dot com> 2012-02-23 16:47:00 UTC --- (In reply to comment #5) > H.J. probably needs to backport a patch or two from mainline. BTW: Please report problems with non-FSF branches directly to their respective authors. There is no -mx32 switch in official 4.6.x, so please try to trigger the x32 specific bug with gcc-4.7.x before reporting it in bugzilla.
