Well, I've looked at it.  This test proggy compiles just fine w/o any
warnings, trying both gcc-2.95.4 (prerelease) and gcc-3.0.2:

    #include <gtk--/base.h>
    #include <gtk--/combo.h>

    const char *const items[] = { "foo", "bar", 0 };

    int main(int, char**)
    {
      Gtk::Combo combo;
      combo.set_popdown_strings(items);
      return 0;
    }

So I suppose it's a gcc-2.96 bug.  It looks like it doesn't choose the
right specialization of Traits<> for array types.
