I was reporting what I found with the tools I have at hand.  My
experience refutes the use of the word "always".  The whole point
of my mentioning "a different runtime" was to show that I understood
that others' mileage varies.  I wasn't saying that I don't believe
what's being reported.

Your complete agreement with each other is not going to have much
effect.  Cygwin source code is not changed by voting.
