Can't rename a file if the target exists on Win32. First rename the target

Browse Source 
2005-11-06  Tor Lillqvist  <tml@novell.com>

	* gtk/updateiconcache.c (build_cache): Can't rename a file if the
	target exists on Win32. First rename the target temporarily, then
	if the renaming of the source to target fails, restore the
	original name for the target.

	* gtk/Makefile.am: Use EXEEXT in the dependency on gtk-update-icon-cache.
