    src/gnome-cmd-main-win.cc: fix for -Wmissing-declarations
    
    src/gnome-cmd-main-win.cc:131:6: error: no previous declaration for 'gint 
gnome_cmd_key_snooper(GtkWidget*, GdkEventKey*, GnomeCmdMainWin*)' [-Werror=missing-declarations]
    
    No prototype appears in headers, so make this static.
