+From: Modestas Vainius <modax@debian.org>
+SUbject: Make hide_symbols to cover all QtWebKit portions
+Origin: vendor
+Author: Timo Jyrinki <timo@debian.org>
+Last-Update: 2013-01-28 (use a similar patch on Qt 5)
+Forwarded: no
+
+Almost everything in Source/WebCore/generated was not build with
+-fvisibility=hidden resulting into redundantly polluted and huge dynamic symbol
+list in libQtWebKit.so.
+
+Therefore, move +hide_symbols configuration parameter upwards in order for it
+to cover everything including the offending Source/WebCore/CodeGenerators.pri
