--clip--
% make
Running dhrystone (Level 1 optimization, without registers)
./dhrystone
Dhrystone(1.1) time for 50000 passes = 35
This machine benchmarks at 1422 dhrystones/second
./dhrystone

^C% make
Running dhrystone (Level 1 optimization, without registers)
./dhrystone
Dhrystone(1.1) time for 50000 passes = 20
This machine benchmarks at 2472 dhrystones/second
./dhrystone
Dhrystone(1.1) time for 50000 passes = 20
This machine benchmarks at 2469 dhrystones/second
