+"LDFLAGS=-Wl,-no-undefined" is better than previous

+
+------- SUGGESTION FOR FORK ISSUE --------------------------
+
+The build process can fails in building images for documentation
+due to fork issue of the octave dll just built. In such case
+I suggest to rebase the built dll's with:
+
+$ find build_tree -name "*.dll" > rebase_list
+
+and after closing all cygwin process, from a dash shell
+
+$ rebaseall -s 'dll|so|oct' -T /full_path/rebase_list
+
+After rebasing the "make" should be able to complete the
+creation of the images and the documentation.
