I remember this was also happening long time ago (about 10 years or
more) in completely different environment of course. Anyway, local
problem with *Cygwin-only* means problem with Cygwin. I rarely use
Cygwin and when I use it, I always stumble upon this. Maybe there is
another reason of why you don't know of other complaints.

what does this mean in core, the documentation is wrong and checksum
is done with different algorithm?
