+	* Makefile (MAKE_VERSION): 20151201
+	  Merge with NetBSD make, pick up

+	  o meta.c: meta_oodate: use lstat(2) for checking link target
+	    in case it is a symlink.

+	* Makefile (MAKE_VERSION): 20151022
+
+	* Add support for BSD/OS which lacks inttypes.h
+	  and really needs sys/param.h for sys/sysctl.h
+	  also 'type' is not a shell builtin.
+
+	* var.c: eliminate uint32_t and need for inttypes.h
+	
+	* main.c: PrintOnError flush stdout before run .ERROR
+
+	* parse.c: cope with _SC_PAGESIZE not being defined.
