+// That header file uses
+//   __attribute__ ((format(printf, 3, 4)))
+// which gets messed up by our override mechanism; this could
+// be avoided by either changing the Android SDK to use the equally
+// legal and valid
+//   __attribute__ ((format(__printf__, 3, 4)))
+// or by refining our printf override to use a varadic macro
+// (which then wouldn't be portable, though).
+// Anyway, for now we just disable the printf override globally
+// for the Android port
