This would tell when Configure was used, not when the sources were fetched.
What about the following ?

if test -d CVS; then
  status="$status "`grep CHANGES CVS/Entries | awk -F/ '{print $4}'`
fi

which gives

   GP/PARI CALCULATOR Version 2.2.4 (development Sat Jun 22 11:03:53 2002)

Or (better, I think)

if test -d CVS; then
  status="$status CHANGES-"`grep CHANGES CVS/Entries | awk -F/ '{print $3}'`
fi

which gives

          GP/PARI CALCULATOR Version 2.2.4 (development CHANGES-1.447)

This assumes that CHANGES is modified whenever a patch is made (true for 99%
of patches).

I can add a (somewhat more complicated) perl script in config/ to get the
exact timestamp of the most recent modified file. It should be relatively
easy to get 'cvs history' to produced something equivalent, but I couldn't
come up with something easy in 2 minutes of 'man cvs'.
