This indicates you do not have the current version of that source file.
Make sure your checkout is up to date.

I have been seeing this on x86 too and I am not really sure why.
It seems to be harmless.

That does not happen for me.  I am using the gcc-3.2 in debian sid.
You must be using some different options or something.  Send config.status.
