This has removes a tiny amount of overhead:

               0.095707 +- 0.000223 seconds time elapsed  ( +-  0.23% )
     $ perf stat -e cpu-clock --repeat 1000 taskset 1 ./src/tac-prev \
         input 2>&1 > /dev/null | grep -F 'seconds time'
              0.1009378 +- 0.0000995 seconds time elapsed  ( +-  0.10% )

Makes sense.
