You implied that "this isn't even coreutils fault".
If it isn't coreutils fault, that would imply that cygwin was doing
something wrong and that coreutils is working around something in
cygwin.
I don't see what that is. If we stripped out all exe handling you would
still apparently put it back into coreutils. The fact that stat() finds
.exe files and unlink() doesn't seems rather irrelevant to me, since
you've more or less produced a wrapper around unlink() but not stat(),
because stat() didn't need one.
The bottom line is that whatever cygwin did or didn't do, the user would
end up seeing the same behavior.
