I was trying to build Emacs pretest in Suse with glib-2.0 and get the
error message.

Please tell us precisely what version of glib is on your system.
Attaching your (compressed) config.log may be helpful.

Configure checks for glib >= 2.6, however it seems g_object_ref_sink may
need glib >= 2.9.

I see the version checks in configure hasn't been updated.
You need at least Gtk+ 2.10 and Glib 2.10.  
g_object_ref_sink was introduced in Glib 2.10.  It was released early 2006, so it is quite old.

I will update configure.in.

People may have to live with older version of glib than 2.10.    I
changed the code

-   g_object_ref_sink (G_OBJECT (wscroll));
+   g_object_ref (G_OBJECT (wscroll));
+   gtk_object_sink (GTK_OBJECT (wscroll));

Then it works.  I did not find any more dependency for glib 2.10.   So
I think it should be something like:

#if GLIB_VERSION_OLD_THAN(2.10)
g_object_ref (G_OBJECT (wscroll));
gtk_object_sink (GTK_OBJECT (wscroll));
#else
g_object_ref_sink (G_OBJECT (wscroll));
#endif

Having all this #ifdefs all over the place is a maintenance problem.  At some point we must move forward.  Considering that 2.10 is well over 5 years old, I don't think requiring it is a hard requirement.
