Just a small clarification: the timings in the log files don't take into
account the compilation time.  Those numbers are just for the execution

The message at the end of the execution of run.scm ("Total run time: ...")
does take compilation time into account (sorry, Peter -- I thought you
were talking about that).

So, the normalized results you see when you feed compare.scm the log
files consider only execution time of the benchmarked programs.

Sorry for the confusion.

Best wishes.
