* 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.

#ifndef _GNU_VERSIONS_H
#define _GNU_VERSIONS_H 1
/* This file exists to define these few macros. Each specifies a version
number associated with the library interface of a piece of the C library
which is also distributed with other GNU packages. These pieces are
both part of the GNU C library and also distributed with other GNU
packages so those packages may use their facilities on systems lacking
the GNU C library. The source files for each piece surround all their
code with `#ifndef ELIDE_CODE' after defining it with this:
#define OBSTACK_INTERFACE_VERSION 1
#if !defined (_LIBC) && defined (__GNU_LIBRARY__) && __GNU_LIBRARY__ > 1
#include <gnu-versions.h>
#if _GNU_OBSTACK_INTERFACE_VERSION == OBSTACK_INTERFACE_VERSION
#define ELIDE_CODE
#endif
#endif
This allows those one to avoid compiling those files when part of a GNU
package not libc, on a system using a GNU C library that supports the
same interface.
Please preserve the format of the comments after each macro. And
remember, if any of these versions change, the libc.so major version
number must change too (so avoid it)! */
