At the time, I was testing simple things, like open(), system(), etc.
I just wanted a baseline to compare against so I could guage the
improvements I was working on at the time; as long as the results were
consistent it didn't matter what the absolute numbers were.  For
example, if I could improve the performance from 10x as much as linux
to only 5x as much as linux, that would be great, but I shouldn't
expect that going from 5x to 2x would be as easy.

One of my other comparisons was against djgpp, for example, whose
performance is sensitive to 95 vs NT, but just knowing that cygwin was
less than 2x the time djgpp took was useful.
