Thanks.  I've fixed the problems you found and also updated the patches
for changes that have happened since last weekend.  Rather than post them
all again, I thought it'd be better to post the delta.  I've left out the
Makefile.in changes because there was a lot of churn in the dependency
list.

I was originally going to wait until Vlad's IRA changes had gone in,
but he kindly offered to let me go first.  Thanks Vlad, and sorry for
the clash.

Retested on x86_64-linux-gnu and mipsisa64-elfoabi.  OK to install?

Richard

I was reading through the series when I saw that RTH was too.  I think
you could safely take his last message as approval, but, in any case, I
too think these patches are OK.  Please give RTH 48 hours to comment,
just in case, and then check in.

Thanks,

The updated patch is ok.
