+Subject: [PATCH 06/11] [Patch, microblaze]: Add SIZE_TYPE and PTRDIFF_TYPE to
+ microblaze.h
+
+Fixes warnings like;
+
+warning: format '%zX' expects argument of type 'size_t',
+but argument 3 has type 'unsigned int' [-Wformat]
+
+Changelog
+
+2013-03-18 David Holsgrove <david.holsgrove@xilinx.com>
+
+ * gcc/config/microblaze/microblaze.h: Define SIZE_TYPE
+ and PTRDIFF_TYPE.
