As always, I can't speak for Corinna, but I suspect that she would be as
thrilled as I would be if you fixed this contrary-to-POSIX problem
without impacting the speed of cygwin's already slow path handling code.
I think it's a pretty hard problem and I really don't care about POSIX
but if this is really that important then maybe someone will step
forward to fix it. The code in question is in path.cc.
