I haven't looked at the patch, but I'm relatively OK with this.  I'd
suggest this text for the comment:

/*
 * Declare the following symbol as public.  This is currently a noop on
 * platforms other than Windows.
 */

Related to this, one thing we should actually really investigate is
the trick used in GLib to avoid going through the PLT for internal
functions.  See:
http://git.gnome.org/browse/glib/tree/glib/makegalias.pl

But that's probably a different patch.

What change would need to be made to the internal symbols?
