Can someone test this small cleanup with trunk on MS-Windows?
This looks correct, but I can't verify it myself.

I've applied your patch to a recent trunk revision (r117347).  It
builds fine and the binary seems to work fine too, but I don't know
what specific test to do...

That's simple:
1) go to *scratch*
2) define a macro to insert something, for example C-x ( a ENTER C-x )
    defines a macro to insert 'a' and newline;
3) ask to execute it 10000 times with C-u 10000 C-x e;
4) while the macro execution is in progress, move the mouse over
    Emacs frame and make sure that the cursor shape is changed and busy
    cursor appears.
5) Do M-x new-frame then repeat 1)-4) but move mouse between two frames
    and make sure that you have busy cursor in both of them.

The cursor's shape doesn't change until I move it (which doesn't seem
like TRT, but the same happens without the patch).

When I move the cursor, its shape change to busy, yes, but when the
execution ends (either by cancelling it with C-g or when it
completes), the shape remains the same (busy).  This problem is
specific to the patched binary.

Here the behavior is equal with or without the patch: the cursor shape
is busy in the original frame (where I started the execution of the
macro) and normal (arrow or I-beam) when I go over the other frame.

Hm....

This is completely different from we have under X where busy cursor
is shown on all GUI frames. Could you also please test this stuff (which
is mostly borrowed from the relevant X code)?

Your second patch has a typo: "Lisp_Oject" should be "Lisp_Object".

With this one, things seem to go better.

When I run the macro:
* The cursor shape doesn't change automatically to busy after any
delay (I've waited for 10-15 seconds).  Ok, this problem isn't new.
* When I move the cursor, its shape changes to busy.

When I cancel the macro, its shape changes back to normal.

With two frames, the shape is busy on both of them while the macro is
running, and changes back to normal on both frames after cancelling
the execution.

I hope so. Installed in trunk as revision 117473. Thank you for testing.

Thanks.

Please test the situation where Emacs shows the hourglass cursor,
i.e. some prolonged operation that causes the hourglass display.  The
specific issues to test are: that the hourglass appears after some
delay, and then disappears as soon as the prolonged operation
completes.  Also, try moving the mouse pointer to another frame and
see what happens.
