I didn't know Dennis Ritchie but I'll bet that, if we were still alive,
he would actually be intelligent enough and pragmatic enough to listen
to rationales for a behavior and, if the problem really interested him
enough, he'd undoubtedly do more than just whine. He'd offer solutions.
I think this subject has been run into the ground. Although I'll grant
you that positing the in-grave behavior of Dennis Ritchie is new, it
isn't helpful, and there is nothing else in this tedious discussion
which has offered any useful new insight, let alone actual code changes.
Heaven forbid that someone would actually look at the Cygwin code and
make informed comments.
