I went back to gcc 4.2.4, 4.1.2, and 3.4.6.  This target failed
at exactly the same point.

So it works on a branch but there is no maintainer.  Merging the
working code onto the truck would be better than letting it
bitrot, wouldn't it?

The code on the trunk is unbuildable and has been
for a long time. 

I'm not an arc user but wonder if it is better to have functional
code on the trunk without a maintainer since it is available than 
non-functional
code on the trunk without a maintainer. :)

If merged, I will at least volunteer to build it once and run
the tests if a free simulator is available.
