--- Comment #6 from Ralf Corsepius <corsepiu at gcc dot gnu.org> 2012-11-03 06:25:33 UTC --- I can confirm i386-rtems4.11-gcc now builds. @Uros: I am inclined to believe this patch probably should be backported to 4.7.x. At least, RTEMS is facing bizarre compilation issues, which I would not want to be related to similar issues as this.
