Perhaps you are not the only one ;-)

HAVE_X_WINDOWS is defined for Emacs built on GNU or Unix systems with
X support enabled.

So you are saying that hourglass cursor doesn't work on Windows?  I
had the impression it did, but it's possible that I was mistaken (I
don't have a Windows port where I'm typing this), so my hand-waving to
explain how it works was just that--hand-waving.  I will try to check
this later today.

So, assuming that hourglass cursor indeed doesn't work on Windows, and
that those snippets are conditioned on X _because_ that feature is not
yet implemented in the Windows port--what is it that you don't
understand in how this feature works on Unix?
