Apparently gtk_misc_set_alignment is deprecated:

https://developer.gnome.org/gtk3/stable/GtkMisc.html

  gtk_misc_set_alignment has been deprecated since version 3.14 and should
  not be used in newly-written code.

  Use GtkWidget alignment and margin properties.

The problem is they don't do exactly the same, but it might be good enough for Emacs.
We use other deprecated stuff, like stock items (deprecated in 3.10).  Every Gtk release deprecates a lot of stuff, those guys can never seem to decide on anything.
I don't know if these should be fixed in emacs-24 or not.
Emacs 24 probably won't compile on Gnome 4, but chances are we have a bugfix release out before Gnome 4, or even 25.1.

My feeling is not.

To be fair, we do kind of the same [ Not sure how we compare in terms of
number of years between declaring something obsolete and actually
removing it, tho.  ]

At least for things we deprecate, I don't expect everyone to immediately
start using the new functionality, because many Elisp packages want to
provide compatibility with older releases, so I think it's OK for Emacs
to use deprecated Emacs interfaces as long as they've been
deprecated recently.

But we should update the code to use the new replacement "as soon as
possible" within the limits of our manpower and the added complexity of
potentially having to support both the old and the new functionality at
the same time (via configure tests, typically).

No, much too late for that.

If/when this is a problem, we can indeed release a bug-fix for it.

Hello.

This is fixed in trunk.  We have one deprecated call left,
gtk_widget_set_double_buffered.

We can't get rid of that without adding Gtk rendering (i.e. Cairo) and only 
rendering in callbacks, that is on expose events.  This is a major job.
