+*** Modified by SBo:
+*** Was: PNG_LIBPNG_VER_MINOR < 5
+*** Now: PNG_LIBPNG_VER_MINOR < 4
+From 70c7f1967f43a94f9f0d6808d6ab5700a120d2fc Mon Sep 17 00:00:00 2001
+From: Chris Liddell <chris.liddell@artifex.com>

+Subject: [PATCH] Bug 695890: Update jbig2dec for modern libpng
+
+libpng 1.5.x and newer hide the internals, and only allow values to be set and
+retrieved via define API calls.
+
+Also tidy up a couple of (benign) compiler warnings.
+
+No cluster diffs.
