+	* random.c, spgrid.[ch]: Fix warnings with hope that I didn't broke
+	  anything. These floats to longs and vice versa casts are starnge
+	  indeed.
+	* isis_pdu.c: As we don't use %z for size_t for now because we support

 	* isis_adjacency.c, isis_lsp.c, isisd.c: Replace XMALLOC && memset
 	  with XCALLOC.
 	* isis_lsp.c (lsp_build_pseudo): Fix adding ES neighbour.
 	* isis_tlv.c: More compact free_tlvs() function.
 	* isis_lsp.c (lsp_build_nonpseudo) : Try to fix one more regression
