This will break more than backwards compatibility with old versions of
setup, but also any scripts that do 'wget -N
https://cygwin.com/setup-x86_64.exe', or equivalent.
It also invalidates a lot of written references to this executable, so
we should probably only make this change with good reason.

You might find the code in [1] a good starting point for an alternate
implementation, which doesn't require renaming the executable.
