Matthias asked to clarify my stance on this patch. The above says that
the patch does not work for architectures with optimized libcs. What it
doesn't say there is that the patch goes a long way to fix architectures
without optimized libcs. It thus presents a good basis for further work
on the bootstrap problem. I would like to see that patch merged.

To be serious, the reason for me having stopped sending glibc patches is
that this essential patch still has not been merged.
