+	* malloc/malloc.c (morecore): Don't attempt recursive realloc of info
+	table when _heaplimit==0 during realloc growing large block.
+
+	* MakeTAGS (extract): Remove /dev/null from xgettext command line.
+	(text-srcs): New variable: extract only C sources from $(tags_sources).
+	(po/$(domain).pot): Depend on that.
+	If it's empty, cp /dev/null $@ instead of $(extract).

+	* sysdeps/unix/sysv/linux/iovec.h: New file.
+	* sysdeps/generic/iovec.h: New file.

+
+	* misc/sys/cdefs.h [__USE_BSD] (const, signed, volatile): Move these
+	macros inside [! __STDC__].
