The line causing these errors is:

tar cfP - -X /scratch/tar.exclude * .[^.]* | (cd /scratch/docbook-xsl-snapshot; tar xfP -)

Googling for the error brought up <http://www.unix.com/unix-advanced-expert-users/56567-problem-tar.html> which suggests it is a problem during the untarring, and adding m to the options (ie tar xfPm -) would help.

Tar's P option tries to preserve all the permissions and timestamps; Pm will do that *except* for the timestamps.

But why is tar trying to call utime in the first place? I see a number of lines much earlier on using touch like this:

touch -t 197001010000 `basename $f`

I'd *guess* that's the root cause. Why is the Makefile trying to set the modification times back to (time_t)0?
