Emacs 24 did change the default behavior, so in Emacs 24, you _must_
set mouse-drag-copy-region non-nil to get the pre-Emacs 24 behavior.

If you can point out what is different in the behavior of Emacs 24
_after_ setting mouse-drag-copy-region wrt double-clicking mouse-1,
please do.  Otherwise, this bug is done.

It wasn't possible to do this in Emacs 23 without "polluting the kill
ring", AFAICS.  In Emacs 23, double-clicking mouse-1 would copy the
text to the kill ring even if mouse-drag-copy-region was nil.  If you
know otherwise, please show how to achieve that (in Emacs 23).

They can -- by customizing mouse-drag-copy-region.  No ifs or buts.

Since this wasn't possible in Emacs 23, you are in effect asking for a
new feature.  The old behavior is completely restored by customizing
mouse-drag-copy-region; after that Emacs behaves on Windows in a way
that is 100% compatible with what it did in Emacs 23 and before.  If
you can show the difference in behavior, please do.  The fact that a
variable needs to be customized is not in itself a change in behavior.
