My previous statement about IA64 isn't a supported architecture any more isn't true, IA64 is still within the ports section.
But I won't reopen this report as I'm not able and willing to keep also track of an non RC architecture for Thunderbird. Keep Thunderbird in a buildable state for the current RC architectures (execpt the already removes architectures here) is taken mostly all the avaiable time and energy. If some non RC architecture want to be more supported by someone please work on usptreaming first the needed patches. Regards Carsten
