Description of problem:

I just tried to compile package glunarclock-0.32.2-2 from 
Redhat Fedora Extras development tree.

The compiler said

1.

glunarclock.c(162): warning #1011: missing return statement at end of
non-void function "delete_event"
glunarclock.c(169): warning #1011: missing return statement at end of
non-void function "close_dialog"

THe source code is

static gboolean
delete_event (GtkWidget  *widget,
              MoonApplet *moon)
{
        gtk_widget_hide (widget);
}

static gboolean
close_dialog (GtkWidget  *widget,
              MoonApplet *moon)
{
        gtk_widget_hide (moon->preferences_dialog);
}

There might be some value in adding a couple of return statements
to these functions.

2.

moondata.c(227): warning #1011: missing return statement at end of
non-void function "delete_event"
moondata.c(234): warning #1011: missing return statement at end of
non-void function "close_data_dialog"

Duplicates.

3.

moondata.c(286): warning #269: invalid format string conversion

The source code is

        g_snprintf(buf, size, "%2d%",(gint)(moondata.NewMoon));

Suggest use %% for % in printf strings.
