It would need to be something like this (assuming the basic approach is
valid):

        GType
        user_defined_class_get_type (void)
        {
          static GType type = 0;
        
          if (!type)
            {
              type = g_type_from_name("UserDefinedClass");
            }
        
          if (!type)
            {
              /** fill in a GTypeInfo structure and register it with the type system **/
              static const GTypeInfo type_info = {
                sizeof (user_defined_class),
                (GBaseInitFunc) NULL,
                (GBaseFinalizeFunc) NULL,
                (GClassInitFunc) user_defined_class_init,
                (GClassFinalizeFunc) NULL,
                NULL,                   /* class_data */
                sizeof (user_defined_class),
                0,                      /* n_preallocs */
                (GInstanceInitFunc) NULL
              };
        
              type = g_type_register_static (G_TYPE_OBJECT,
                                             "UserDefinedClass",
                                             &type_info, 0);
            }
        
          return type;
        }

In the event that you do get the type via g_type_from_name, you want to
set the static variable and return a valid GType pointer.

I've tried checking GtkGLExt out of CVS and making this modification.
However, po/Makefile.in.in doesn't like my version of autotools. (What
$(mkinstalldirs) resolves to has changed in a way that is incompatible
with how it is used here.) What do I need to do to update this file? I
tried gettextize; but that added a rather large number of files that
didn't exist previously.
