So it seems that the current bug probably has the same cause as 
bug#16014.  I've installed the fix (but using the window-system 
function) in the release branch as bzr revision 117465.

When I start up the Cygwin-w32 build of emacs, the image at the top of 
the splash screen often fails to display.  The following patch fixes it:

Is this still OK for the native Windows build?  If so, is it OK to 
install it in the release branch?
