+ READLINE PATCH REPORT
+ =====================
+
+Readline-Release: 6.3
+Patch-ID: readline63-005
+
+Bug-Reported-by: Juergen Daubert <jue@jue.li>
+Bug-Reference-ID: <20140303180430.GA7346@jue.netz>
+Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-readline/2014-03/msg00002.html
+
+Bug-Description:
+
+There are still applications using the deprecated Function/VFunction/etc.
+typedefs in rltypedefs.h. This patch restores the typedefs, but attempts
+to mark them as deprecated using gcc/clang attributes. Thanks to Max Horn
+for the suggestion.
+
+Patch (apply with `patch -p0'):
