I don't recall reading anything about posix allowing the elimination of such paths.
If I have an application layer on top of linux that processes those double slashes, it may or may not work depending on the underlying OS? That wouldn't be very portable w/r/t a Portable OS Information eXchange standard. I also specified the elimination of the single dots after a slash which in reality don't have the same meaning as the slash. It would useful if bugs were not closed before asking for more information. I've seen many bugs over the years that were closed when they were real bugs that came back and bit the project hard, including bugs that were closed out because I hadn't sent them through cygwin's list first when I knew they were not bugs in cygwin.
