No I cant, sorry. I suspect this may be environmental. I tried again and it failed somewhere else. I tried a third time on a different disk and the build completed fine. I tried a fourth time on the original disk and it worked fine too. So I cant reproduce it any more. I have built gcc many times on many machines and don't normally have any trouble.
