------- Comment #8 from The Written Word  2006-12-02 15:44 UTC -------
Some updates on these two bugs (static_cast and Glib::unwrap ambiguities):

o static_cast needs to be removed at quite a lot of other places, too. I didn't
  check if these were all enum related casts.

o The overload ambiguity bug in the Sun compiler has been filed as

  4886310 Overloading ambiguity error with usage of template function with
const vector

  Unfortunately I don't have access to the bug description and activity, but it
  is supposedly fixed in the latest compiler patches. Still a workaround is
  needed for the other broken compilers as well.

o The workaround is to explicitly instantiate the function template with the
  proper argument. There seems to be another bug in the game requiring full 
  Namespace resolution. For example:

 bool Uri::equal(const Glib::RefPtr<const Uri>& uri) const
 {
-  return gnome_vfs_uri_equal(const_cast<GnomeVFSURI*>(gobj()),
Glib::unwrap(uri));
+  return gnome_vfs_uri_equal(const_cast<GnomeVFSURI*>(gobj()),
Glib::unwrap<Gnome::Vfs::Uri>(uri));
 }

  Perhaps some m4 conversion tricks would be able to get the template parameter
  as an argument to Glib::unwrap.

o glibmm has similar Glib::unwrap (indirect) issues, e.g. some header files
need
  to explicitely instanciate the proper template, too, to assist the compiler
in
  its choice.

When I get it to build on the remaining platforms, I can post a patch here, but
it would be against the gtkmmproc generated files.
