2004-11-30  Hans Breuer  <hans@breuer.org>

	* gdk/win32/gdkpixmap-win32.c : remove the disputable memset at
	the end of gdk_pixmap_new() - on X11 the bits are not initialized
	either - fixes bug #145107

	* gtk/gtkfilesystemwin32.c : add an idle handler to emit "volumes-changed"
	when drives are plugged in or removed. Fixes bug #137815
