	* desktop.cc (DesktopSetupPage::OnInit): Drop CoInitialize call here.
	* main.cc (main_display): Use InitCommonControlsEx rather than
	InitCommonControls per MSDN.  Call CoInitializeEx and create IShellLink
	instance here to workaround a problem on Windows 7.  Release IShellLink
	instance and call CoUninitialize on exit.
	* mklink.cc (sl): Change to global variable.  Drop call to
	CoCreateInstance here.  Check if sl is valid before using it.
