+APPROVE COMMIT 21.5
+
+This patch has been committed.  When trying to open very large image
+files (or image files with header files that claim the image is very
+large), we multiply length times width to get the number of pixels in
+the image (and possibly multiply that number if a pixel occupies more
+than 1 byte).  The multiplication can overflow, resulting in passing
+negative or insufficiently positive size values to malloc.  This patch
+checks whether the multiplication will overflow.  If so, XEmacs
+refuses to attempt to load the image.
+
+(Patch taken from upstream, already applied there)
