From bdf8cb302ab7c8f11b676f93da482cd4a9405ce4 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2003/2008] jdk: Allow using a system-installed libpng
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Patch stolen (and some typos corrected) from debian patch,
which itself was a backport from:
http://hg.openjdk.java.net/jdk9/jdk9/rev/bfc1c131e540
http://hg.openjdk.java.net/jdk9/jdk9/jdk/rev/5e503831b142
Issues fixed on top of debian patch:
* the default when --with-libpng= is not given works
* using the bundled libpng works
Upstream-Status: Backport
