- guess I have a breakin;-)
FWIW here are some benchmarks results (a PII-laptop) of the
stdio benchmark suite that come with sfio-2000 (I had to
disable 2 seek tests because they crashed the sfio version).

It is possible to compile many (well I tried only a few of
course) programs with a small amount of work with the sfio
version of stdio instead of the regular stdio in libcygwin.
