It doesn't address issue of old code that uses GTK, that was written
for old GTK,
and/or was built with old GTK (like gtkmm, if I understand that issue
correctly).
it does, that is what this thread is about. the current code in CVS
doesn't adress this, which is why Murray Cumming started the
"GTK_FLOATING
broken in 2.9?" thread.
the "ABI and API for g_object_ref_sink()" thread adresses this issue by
providing a proposed solution and an analysis of the impact on various
glib/gtk version combinations.
