question on build warning

Is this warning something to be concerned about?

I built using the --time=ftime option on the Configure line in the root 
folder /home/owner/math/pari-2.18.0-251-g5d3c5ac62a/

% ./Configure --tune --mt=pthread --time=ftime --with-gmp --with-readline

And noticed this occurred twice.
