	* Makerules (lib%.so: lib%_pic.a): Pass -soname switch giving the
 	library's name including $(libprefix) and major version number.

	* locale/locale-ctype.c (allocate_arrays): Use xmalloc and bzero
 	in place of xcalloc.

	* Makeconfig (prefix, exec_prefix, libprefix): Instead of
 	`ifndef', use the $(origin) function to only set these if they are
 	undefined, and not if they are defined to empty.

	* gnu-versions.h: New file.
	* features.h (__GNU_LIBRARY__): Increase value to 5.
