Make bench timings in 2.2.6 are incorrect due to missing gettime() at the
start of bench files. Either test the same version of GP on both machines, or
copy the test/ directory from 2.2.7 CVS to your 2.2.6 tree [ you'll get many
"BUGs" due to the new gettime() instruction, but timings should be accurate
this time ]
