Again, I cannot have had a look into the sources. They are not available to the public.
I got the ideas
a) from the UWIN mailing list (the add .exe on close patch, see
b) from playing with the binaries (rename() and link() logic)

Glenn and David commented a bit on those on request. Their comments were something like: "Don't add the .exe extension to "b" on rename("a.exe", "b")! Specifying an .exe extension indicates that the users knows what he's doing." [I had first added .exe to b, because I thought UWIN was wrong in this case.]
Again, no code and not even implementation details.
I believe that wouldn't have helped me either, as I don't know their underlying data structures and they do not know Cygwin's.
I've invented my own implementations.
There are no other UWIN related patches than those.
All other patches are bug fixes or small corrections to make Cygwin behave more consistent.

I was just trying to be picky :-)

Are the issues cleared now?
