Bootstrap failures on ia64 (was Re: Readiness of tree-ssa)

[Richard Guenther <rguenth at tat dot physik dot uni-tuebingen dot de>]

I just checked 3.4 branch and get exactly the same failure.  And I can't
find any trace of _Unwind_Resume_or_Rethrow being defined or used anywhere
but as extern declaration in unwind.h and

unwind-sjlj.c:#define _Unwind_Resume_or_Rethrow	_Unwind_SjLj_Resume_or_Rethrow

anyone has an idea what I'm doing wrong? This is Debian unstable, binutils
is 2.14.90.0.7-3, libc 2.3.2.ds1-10.0.

Thanks,

Richard.
