(In reply to comment #1)

 Is this with the first build of libgcc?  I.e. is it likely that I'll

 see this with just a cross-build?

 

 Also, can you please check whether the patch in

 http://gcc.gnu.org/ml/gcc-patches/2012-11/msg02188.html solves the problem,

 as it does for alpha-linux?



I'll reply myself: apparently-yes, yes and yes; cross from x86_86-linux.

And need to add -fpreprocessed to the cc1 command-line above or there's an

unhelpful preprocessor error.  So, once Jakub has committed that patch, please

verify that this is sufficient (besides required).  Thanks.

Native build is finished as well. Jakub's patch fixes the issue.
