+Subject: [PATCH] Bug 702985: drop use of FT_CALLBACK_DEF() def
+
+From 2.10.3, Freetype disappeared the FT_CALLBACK_DEF() macro, which is what
+we used when defining our callbacks from Freetype.
+
+No guidance forthcoming from the Freetype developer who made those changes,
+so change to explicitly declaring the callbacks file static.
+
+Should fix the reported build failures.
