+Subject: [PATCH] Build fails with libxml2 version 2.12.0 due to API change
+ https://bugs.webkit.org/show_bug.cgi?id=265128
+
+Reviewed by Philippe Normand.
+
+Starting with libxml2 2.12.0, the API has changed the const-ness of the
+xmlError pointers, which results in a build error due to a mismatched
+type in the parsing error callback. This papers over the difference by
+using preprocessor conditionals.
+
+* Source/WebCore/xml/XSLTProcessor.h: Use const when building against
+  libxml2 2.12.0 or newer.
+* Source/WebCore/xml/XSLTProcessorLibxslt.cpp:
+(WebCore::XSLTProcessor::parseErrorFunc): Ditto.
