The attached patch adds printing of the difference in time between BASERUBY and RUNRUBY when make benchmark is run.

This makes it easy to quickly determine if changes have increased or decreased the speed of ruby.

This sound good idea.
'make benchmark' result is not stable. then, I always use "-r 5". So, It would be better if we can compare average performance.
